Replace FDT tree parsing with gpio_map_gpios implementation in mv_gpio driver

This patch replaces in-driver FDT parsing, which was
needed for setting initial values on GPIO pins.
Now FDT is parsed by generic kernel code, pins are set
by invoking gpio_map_gpios method.

Update mv_gpio driver to new FreeBSD API

This patch implements and exports functions described
in gpio_if.m file. It also uses new gpiobus_attach_bus function
instead of adding gpioc and gpiobus as children. It removes
ulgy reading SoC ID and related if..else, so it depends only on
data read from FDT.

Enable Marvell gpio driver to work with many controllers

This patch moves all global data structures into mv_gpio_softc,
and puts device_t parameter to functions calls everywhere where needed.
As a result, we can create multiple driver instances.

Removed names in function declaration to keep style.

Improve interrupt and resource allocation in Marvell GPIO driver

This patch adds support for more than one interrupts
in GPIO controller. It reads necessary information (such as cell size)

Note that interrupts are still not working, but this patch makes
one good step in correct direction

sys/arm: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
