drm/radeon: fix resume on some rs4xx boards (v2)
commit acf88deb8ddbb73acd1c3fa32fde51af9153227f upstream.
Setting MC_MISC_CNTL.GART_INDEX_REG_EN causes hangs on
some boards on resume. The systems seem to work fine
without touching this bit so leave it as is.
v2: read-modify-write the GART_INDEX_REG_EN bit.
I suspect the problem is that we are losing the other
settings in the register.
