Convert driver to use DT_INST_ defines. As part of this conversion we
remove the Kconfig options for per GPIO controller enables and instead
get that information from device tree. This means we now disable each
GPIO controller by default in the DTS and have each board dts enable the
GPIO controller ports it needs.

All GPIO controller drivers support DTS so we can select HAS_DTS_GPIO
at the GPIO driver subsystem level rather than for each specific driver.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

Most of these are from source'ing a file within an 'if GPIO', and then
adding another 'depends on GPIO' within it.
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. There are no "conditional includes" in Kconfig, so
'if FOO' has no special meaning around a 'source'. Conditional includes
wouldn't be possible, because an 'if' condition could include (directly
or indirectly) forward references to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.
This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'
Piggyback a missing 'source "drivers/gpio/Kconfig.imx"'. This file
wasn't included anywhere previously.

Add a set of Kconfig symbols that allow us to set that the GPIO
driver/SoC support DTS (HAS_DTS_GPIO) and that drivers that need/use
GPIO support DTS as well (HAS_DTS_GPIO_DEVICE).

These are more consistent with naming used by other ports (uppercase,
short), and some existing software relies on them to be exactly those.
This change is a follow up to the discussion on the Zephyr mailing
list, calling to establish consistent naming conventions for Zephyr
devices, and is a small step in that direction.

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.

Adds a new mcux gpio driver that can be used for k64 and other Kinetis
SoCs. This driver uses mcux CMSIS register accesses to the GPIO and PORT
modules. Some of the logic from the k64 gpio driver was reused and
refactored (mainly flag parsing and callback handling).
