To support interrupt-based GPIO callbacks in the nRF5x series one needs
to use the GPIOTE module, which has a series of channels that can be
programmed to trigger interrupts on level changes.
This commit adds basic support for the GPIOTE module within the nRF5x
GPIO driver, as well as callback support in order for basic buttons and
switches to work.

To make way for the upcoming blinky and GPIO support for nRF5x-based
boards, this change addresses the hardcoded dependencies in Kconfig
default configurations of the different boards, moving the common option
defaults to the SoC default configuration itself.

This patch addresses the potential name conflict between the redefined

Directly use AON GPIO trigger instead of IPM.
In the past, SW did not allow arc to receive AON GPIO interrupt.
So, interrupt from BMI160 was routed to x86 cpu. Then, x86 cpu
passed the event to arc through IPM. But, SW was updated and arc
is able to directly receive interrupt from AON GPIO now. So, IPM
is not needed any more. Let's remove IPM related code and use
GPIO as the default trigger source.
This change is on top of the bmi160 sample app change to not use
IPM.

The nRF RTC driver, which is used a system clock driver due to the lack
of SysTick hardware on the SoC, was using too much CPU time in its
_timer_idle_exit() implementation due to the use of 64-bit arithmetical
operations. This was causing the ISR wrapper to add excessive latency to
critical interrupts, causing BLE controller asserts.
This patch addresses the issue by using exclusively RTC ticks instead of
OS ticks, thus avoiding the necessity to convert during
_timer_idle_exit() calls, which are the most critical to interrupt
latency.
In addition the driver is now able to detect setting tick events in the
past due to it being interrupted by a higher priority context, and will
reschedule and trigger the ISR at the same time.

The FIRQ stack needs to be saved and restored
when performing sleep operations.

is made to refer to _firq_stack.

In order to keep the initialization process light-weight, remove
net_buf_pool_init() and instead perform the initialization of the pool
and buffers in a "lazy" manner. This means storing more information
in the pool, and removing any 'const' members from net_buf. Since
there are no more const members in net_buf the buffer array can be
declared with __noinit, which further reduces initialization overhead.

Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu. Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom. Do not present pseudo generators if a true random generator
is presented.
This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.
In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.
Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.

Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".
This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:
NET_BUF_POOL_DEFINE(pool_name, ...);
Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.
This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.

The existing explicit sys_rand32_init() function runs immediately after

Kinetis SoCs contain one or more PORT modules to handle pin muxing and
pin configuration. Unlike the existing k64 pinmux driver, this driver
handles each PORT module individually and can be used for other Kinetis
SoCs.
This driver uses KSDK CMSIS register accesses to the PORT module rather
than the KSDK PORT driver (fsl_port.h), because the Zephyr pinmux
interface contains both set() and get() functions to access the pin
configuration. The KSDK PORT driver only contains a set() function
(which is a very thin static inline function to modify the PCR
register), therefore building a shim on top of it would result in a
strange mix of using the KSDK PORT driver for the set() and a direct
CMSIS register access for the get().
