most code come from MCG, which use dsi_hw_context to save/restore
panel registers at early_suspend/late_resume.

Test method

early_suspend: echo mem > /sys/power/state

HACK: gfx: Adjust HDMI hdisplay/vdisplay values

The HDMI code doesn't follow the KMS desing correctly, hence the values
stored in the mode structure are incorrect. Adjust the "user" mode
hdisplay/vdisplay and their crtc counterparts to match the framebuffer
size. This "fixes" vblank counter comparisons for HDMI, thus fixing page
flip completion detection, and this also allows the overlay to be
clipped "correctly".

This makes assumptions on how the panel fitter willl be programmed.
Based on a cursory examination of the HDMI code, it will only work
as long as the IPIL_TIMING_SCALE_ASPECT scaling mode is selected.

Add check reset function for msvdx firmware

When fence lockup is triggered by the msvdx firmware, it reaches an
unrecoverable state that requires a firmware reload so that it can
continue operating without resetting the device.

This scenario is seen when playing some corrupted media clips which
cause the media stack to fail.

Once the firmware is reloaded it will continue decoding when possible
and next attempts to play will be successful
