drm/amdgpu/gfx10: new approach to load pfp fw (v4)

Browse Source 
gfx10 allows to only upload pfp jumptable while save the whole
pfp image at gtt memory.

v2: program CP_PFP_IC_BASE_CNTL to default value
v3: switch to use amdgpu_bo_create_reserved to create pfp fw bo
v4: split common code from gfx10 code
