MLK-21509-3 drm/imx: dpu: kms: Add auto control mode debugfs CRC support

This patch adds auto control mode debugfs CRC support based on
DPU Signature units.  The evaluation window is the same to the
display region as indicated by drm_crtc_state->adjusted_mode.
The CRC data count is three when single DPU display stream is used,
while six when the pixel combiner(dual DPU display streams) is used.
Each data shows the CRC value for the 8 most significant bits of
red/green/blue channel of the entire evaluation window, which reflects
how DPU Signature unit reports CRC values.
