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.
