drm/radeon: Add CP init for CIK (v7)
Sets up the GFX ring and loads ucode for GFX and Compute.
Todo:
- handle compute queue setup.
v2: add documentation
v3: integrate with latest reset changes
v4: additional init fixes
v5: scratch reg write back no longer supported on CIK
v6: properly set CP_RB0_BASE_HI
v7: rebase
