drm/amdgpu: correct ih_chicken programming for vega10/vega20 ih blocks

Browse Source 
IH_CHICKEN.MC_SPACE_FBPA_ENABLE field is only
valid when IH_RB_CNTL.MC_SPACE is programed to 0x3,
frame buffer physical address. For both bus address
and gpu virtual address, don't program MC_SPACE_FBPA_ENABLE
field
