Add support for drm panels to tilcdc. Adding the support on top of the
existing bridge support needs only couple of lines of code when using

Brightness couldn't change when booting up in DC mode.
It was because "psr_enabled" flag was not set to true before
setting vsc packet revision, causing packet rev setup was skipped.
Now instead of checking the psr flag, it checks if the DPCD_REV >= 1.2
and set the vsc packet revision.

When user-mode is using 8bpc, the hardware represents it internally
using a higher bit depth. This causes problems when comparing CRCs for
color managment tests.
We need to disable dithering as well, since it makes CRC values
non-deterministic.
It's easy to see why dithering needs to be disabled, The reason why
truncation also needs to be enabled is better described with an example.
Consider the folowing which tests the color transform matrix (CTM):
Expected CRC = FB_A -> Degamma (Bypassed) -> CTM (Bypassed)
|
v
Obtain CRC <- Regamma(Bypassed)
Actual CRC = FB_B -> Degamma (Bypassed) -> CTM (0.5*Identity)
|
v
Obtain CRC <- Regamma(Bypassed)
FB_A contains a solid red color at half intensity (127 @ 8bpc)
FB_B contains a solid red color at full intensity (255 @ 8bpc)
We expect that Expected CRC = Actual CRC, but that's not the case. When
the CTM is applied, the output is at half intensity, but also at a
higher bit depth within hardware. i.e. 255/2 = 127.5: not representable
in 8bpc, but can be at 10bpc. This causes the two CRC's to be different.
The solution is to truncate the output bit depth to the same as input
when enabling CRC capture. Since Linux only supports 8bpc, hard code
that for now.
