HFCLK and LFCLK states with respect to the requested
sources.

Added Kconfig option and implementation to support a
non-blocking startup of 32KHz crystal oscillator.
This will reduce the time from boot to application start
while the crystal startup happens in background.

nRF52840 USBD requires power events to start USB enumeration.
Add APIs to enable/disable the power events, read the USB VBUS detect
and output power ready statuses which can then be used by the USB driver
in the enumeration sequence.

Fix return value to -EBUSY instead of 0 when releasing a
reference but not physically turning off the clock.

If the LF clock was already started, but wasn't initialized with
_k32src_start yet, allow it to run once. This is needed because if a
soft reset is triggered while watchdog is active, the LF clock will
already be running, but won't be configured yet (watchdog forces LF
clock to be running).
If the LF clock isn't configured with _k32src_start, the nRF5 RTC
won't count and the whole system will malfunction, as the kernel
depends on the clock source being working properly.

Convert driver to use the CMSIS NVIC APIs rather than the internal ones
so we can remove them in the future.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.
New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.
Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

Also switch the controller, uart and clock drivers to use the common
header definitions.

In the Nordic Semiconductor's nRF5x series SoC clock control
system can source the system clocks from a range of internal or
external high and low frequency oscillators and distribute them
to modules based upon a module’s individual requirements.
In this commit the implementation adds support for 16MHz
peripheral clock, 32.768 kHz RC oscillator, and 32.768 kHz
crystal oscillator clock sources.
16MHz peripheral clock is required to use the 2.4GHz Radio
peripheral. 32.768 kHz RC or crystal oscillator clock source
is required to use the real time counter peripheral.
