intel/gm45: Fix interpretation of VT-d disable bit
When configuring the GTT size for the integrated graphics, the state
of VT-d was read wrong. Bit 48 of CAPID0 (D0F0) is set when VT-d is
_disabled_.
In the log of a VT-d enabled roda/rk9 we have now:
[...]
VT-d enabled
[...]
IGD decoded, subtracting 32M UMA and 4M GTT
[...]
Without this patch, only 2M GTT were reported.
