drm/amd/display: Added pixel dynamic expansion control.
[Why] To compare the crc of the framebuffer data at input of display pipeline with the crc of the otg, we need to disable pixel formatter's dynamic expansion feature during crc capture and keep it enable in the normal operation. [HOW] Expose a new interface in DM and dc for pixel formatter (fmt dynamic bitdepth expansion control). Interface control the FMT_DYNAMIC_EXP_EN bit, during crc capture keep it disabled.
