drm/i915: Add missing mask when reading GEN12_DSMBASE

Browse source

DSMBASE register is defined so BDSM bitfield contains the bits 63 to 20
of the base address of stolen. For the supported platforms bits 0-19 are
zero but that may not be true in future. Add the missing mask.

v2: Use REG_GENMASK64()
