[PATCH 034/459] drm/amdgpu/gfx10: new approach to load ce fw (v4)

[Alex Deucher]

From: Hawking Zhang <Hawking.Zhang at amd.com>

gfx10 allows to only upload ce jumptable while save the whole
ce image at gtt memory.

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