drm/amd: Add ucode DMCU support
DMCU (Display Microcontroller Unit) is a GPU chip involved in
eDP features like Adaptive Backlight Modulation and Panel Self
Refresh.
DMCU has two pieces of firmware: the ERAM and the interrupt
vectors, which must be loaded seperately.
To this end, the DMCU firmware has a custom header and parsing
logic similar to MEC, to extract the two ucodes from a single
struct firmware.
