Carles Cufi 6a23e82186 drivers: gpio: Set the line to the pull by default
To avoid glitches in the lines, set the line to the pull specified
before actually changing the line's direction (in/out) so that no
unexpected pulses are generated.

Marcus Shawcroft 142bce58a2 gpio/nrf5: Fix GPIO_ACCESS_BY_PIN behaviour
Adjust the implementation of gpio_pin_read() to return 0 or 1 rather
than 0 or 2^pin.  This ensures consistent behaviour with other gpio
device drivers, and conforms to the behaviour documented in gpio.h by
the previous patch.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
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.

Jira: ZEP-1457

Carles Cufi 129a2f0bb6 gpio: nrf5x: Add support for GPIOTE and GPIO callbacks
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.

Andrew Boie 0b474eef9c kernel: deprecate old init levels
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.

Ricardo Salveti d25d62a0e9 gpio/nrf5: set and clear just the specific gpio pin
Don't use the previous reg value when setting up just one specific pin,
as it can have a side effect on other gpio pins.

Tomasz Bursztyka a6cf6038e3 gpio: Remove obsolete API 1.0 callback mechanism
In 1.0 you could set only one callback on the whole gpio controller. It
was impossible for another sub-system to add another callback, without
overwritting an existing one.

Such API has been obsolete for a long time and no one is using it
anymore. Thus removing it entirely.
