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

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.

Merge ^/head r320573 through r320970.

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 platfo

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.

Start to move the arm *_mp.h to be names *_machdep.h. These will be used
by the reworked pl310 driver interface in
https://reviews.freebsd.org/D11546

Add a delay count to the last few places. This will help make MULTIDELAY
a requirement on armv6 with PLATFORM.

Merge ^/head r319548 through r319778.

Port the Xilinx code to use PLATFORM and PLATFORM_SMP. This will help move
it to be part of the armv6 GENERIC kernel.

Merge ^/head r309817 through r310168.

Add the missing void to function signatures in much of the arm code.

Restrict where we need to define fdt_fixup_table to just PowerPC and
Marvell.

Remove bus_dma_get_range and bus_dma_get_range_nb on armv6. We only need
this on a few earlier arm SoCs.
