In addition to using the SCDC helpers to enable support for scrambling
for HDMI 2.0 modes, take into account the high pixel clocks when
programming some of the registers.

The SOR found on Tegra186 is very similar to the one found on Tegra210
and earlier. However, due to some changes in the display architecture,
some programming sequences have changed and some register have moved
around.

Current generations of Tegra do not support deep color modes, so force
8 bits per color even if the connected monitor or panel supports more.

The SOR1 introduced on Tegra210 supports HDMI 2.0 and DisplayPort. Add
HDMI support and name the debugfs node after the type of SOR. The SOR
introduced with Tegra124 is known simply as "sor", whereas the
additional SOR found on Tegra210 is known as "sor1".

The TRM lists indexed registers without an underscore to separate name
from index. Use that convention in the driver for consistency.
While at it, rename some of the field names to the names used in the
TRM.

The SOR allows the computation of a 32 bit CRC of the content that it
transmits. This functionality is exposed via debugfs and is useful to
verify proper operation of the SOR.

Add support for eDP functionality found on Tegra124 and later SoCs. Only
fast link training is currently supported.
