drm/amdgpu: Clean up KFD VMID assignment

The KFD VMID assignment was hard-coded in a few places. Consolidate that in
a single variable adev->vm_manager.first_kfd_vmid. The value is still
assigned in gmc-ip-version-specific code.

drm/amdgpu: enable ABGR and XBGR formats (v2)

Add support for DRM_FORMAT_{A,X}BGR8888 in amdgpu with amd dc disabled

(v2) Crossbar registers are defined and used to swap red and blue channels,
keeping the existing coding style in each of the dce modules.
After setting crossbar bits in fb_swap, use bitwise OR for big endian
where required in DCE6 and DCE8 which do not rely on REG_SET_FIELD()
