Update the programming sequence to allow DMCU firmware to be loaded by
PSP. This code detects whether the firmware is loaded and does a check
to verify the expected interface version and checks for correct response
from micro controller.

Added registry key method to allow force loading of firmware from kernel
mode driver for test purposes. This is old method of firmware loading
without PSP.

Moved some init sequences into dc/dmcu.

Changed loading sequence to initialize IRAM after firmware completely
loaded. Firmware will now disable features that use IRAM
until initialized.

Currently in the case where some of the allocations fail for dce110_tgv,
dce110_xfmv, dce110_miv or dce110_oppv then the exit return path ends
up leaking allocated objects. Fix this by kfree'ing them before returning.
Also re-work the comparison of the null pointers to use the !ptr idiom.

For DP active dongles, the dpcd dongle caps are read but not
used to validate mode timing. This addresses this.

In particular, this change fixes light up on the HDMI 4k TV
connected through DP active dongle. Since the 4k TV defaults
to YCbCr420, which the dongle don't support.

This change does not address MST cases, a more generalized
approach must be taken for that.
