Extend the imx6 gpc->gic interrupt controller fixup of fdt data at runtime
to work with the pmu and tempmon nodes as well as the soc node. This allows
interrupts to work on the pmu and tempmon devices even though we don't have
a driver for the low-power gpc interrupt controller (which is not a problem
because we also don't have support for entering deep power-down modes where
it gets used).

Apply a runtime patch to the FDT data for imx6 to fix iomuxc problems.

The latest imported FDT data defines a node for an iomuxc-gpr device,
which we don't support (or need, right now) in addition to the usual
iomuxc device. Unfortunately, the dts improperly assigns overlapping
ranges of mmio space to both devices. The -gpr device is also a syscon
and simple_mfd device.

At runtime the simple_mfd driver attaches for the iomuxc-gpr node, then
when the real iomuxc driver comes along later, it fails to attach because
it tries to allocate its register space, and it's already partially in
use by the bogus instance of simple_mfd.

This change works around the problem by simply disabling the node for
the iomuxc-gpr device, since we don't need it for anything.

Fix fallout from the import of fresh dts source files from linux 4.15. It
appears that node names no longer include leading zeroes in the @address
qualifiers, so we have to search for the nodes involved in interrupt fixup
using both flavors of name to be compatible with old and new .dtb files.

(You know you're in a bad place when you're applying a workaround to code
that exists only as a workaround for another problem.)

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.

Add external PLATFORM access on arm, and use it in the pl310 driver.

This allows multiple instances of SoCs that use the pl310 driver to be
built within the same kernel:

* Add access to the platform_t object from outside platform.c
* Use this with the pl310 driver

There is a new platform_pl310 interface to replace the existing code. SoCs
need to implement the init method, and if they have special requirements to
write to the two registers we care about will also need to implement the
write_ctrl and write_debug methods.
