drm/xe: Move register MMIO into xe_tile
Each tile has its own register region in the BAR, containing instances
of all registers for the platform. In contrast, the multiple GTs within
a tile share the same MMIO space; there's just a small subset of
registers (the GSI registers) which have multiple copies at different
offsets (0x0 for primary GT, 0x380000 for media GT). Move the register
MMIO region size/pointers to the tile structure, leaving just the GSI
offset information in the GT structure.
