drm/amd/display: fbc state could not reach while enable fbc
[WHY] fbc is within the data path from memory to dce. while
re-configure mc dmif, fbc should be enabled. otherwise, fbc
may not be enabled properly.
[HOW] before re-configure mc dmif, disable fbc, only after
dmif re-configuration fully done, enable fbc again.
