sys/powerpc: 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.

Actually add the mpc85xx_get_platform_clock() function.

Follow up r319935 by actually committing the mpc85xx_get_platform_clock()
function. This function was created to facilitate other development, and I
thought I had committed it earlier.

Some blocks depend on the platform clock rather than the system clock.
The System clock is derived from the platform clock as one-half the
platform clock. Rewrite mpc85xx_get_system_clock() to use the new
function.

Add a helper function to get system reference clock

Many devices are clocked from the SoC's platform clock / 2. Some device nodes
include their own clock-frequency property, while others are dependent on the
SoC's bus-frequency property instead. To simplify, add a helper function to get
this clock.

Simplify the page tracking for VA<->PA translations.

Drop the tracking down to the pmap layer, with optimizations to only track
necessary pages. This should give a (slight) performance improvement, as well
as a stability improvement, as the tracking is already mostly handled by the
pmap layer.

Add NXP/Freescale DIU driver for PowerPC SoCs

Summary:
This enables some features of the DIU, using a static configuration,
specified either via a 'edid' property on the 'display' FDT node, or a
'video-mode' environment variable (bootarg). 'video-mode' was chosen because it
matches u-boot's naming, so it can be set with:

setenv bootargs video-mode=${video-mode}

at the u-boot CLI.

Mouse cursor is not supported currently, as a hardware cursor is not supported
by framebuffer VT yet. Currently it only supports a 32bpp ARGB (actually BGRA)
format, and only a single composite plane, at up to 1280x1024.

Merge MPC85XX and QorIQ config options

Summary:
MPC85XX and QorIQ are very similar. When the DPAA dTSEC driver was
added, QORIQ_DPAA was brought in as a config option to support the differences
in hardware register settings between QorIQ (e500mc-, e5500- based) SoCs and
QUICC (e500v1/e500v2-based) SoCs, particularly in the Local Access Window (LAW)
target settings.

Unify these settings using macros to hide details and ease porting, and use a
new function (mpc85xx_is_qoriq()) to distinguish between QorIQ and QUICC SoCs at
runtime.

An alternative to using the function could be to use a variable initialized at
platform attach time, which may incur less overhead at runtime. Since it's not
in the critical path once booted, this optimization doesn't seem necessary at
first pass.

Extend idle support for newer Book-E cores.

Newer Book-E cores (e500mc, e5500, e6500) do not support the WE bit in the MSR,
and instead delegate CPU idling to the SoC.

Perhaps in the future the QORIQ_DPAA option for the mpc85xx platform will become
a subclass, which will eliminate most of the #ifdef's.
