drm/radeon: add initial ucode loading for CIK (v5)
Currently the driver required 6 sets of ucode: 1. pfp - pre-fetch parser, part of the GFX CP 2. me - micro engine, part of the GFX CP 3. ce - constant engine, part of the GFX CP 4. rlc - interrupt, etc. controller 5. mc - memory controller (discrete cards only) 6. mec - compute engines, part of Compute CP V2: add documentation V3: update MC ucode V4: rebase V5: update mc ucode Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
