drm/amdgpu: Merge get_reserved_allocation to get_vbios_allocations.
Some ASICs need reserved memory for firmware or other components,
which is not allowed to be used by driver.
amdgpu_gmc_get_reserved_allocation is to handle additional areas.
To avoid any missing calling,
merged amdgpu_gmc_get_reserved_allocation to
amdgpu_gmc_get_vbios_allocations.
