drm/xe: Drop old Xe GT ID macros

Browse source

XE_GT0 and XE_GT1 are old macros that were used for hardcoding specific
GTs during early development of the driver; neither should be anymore
since the driver shouldn't be making assumptions about what ID numbers
correspond to specific types of IDs.

 * XE_GT0 was only being used in the GuC init code to skip reading the
   hwconfig table on more than one GT.  Comparing the GT against
   xe_root_mmio_gt(xe) is a more direct way to ensure this happens on
   just a single GT per device (and should work even if the ID numbers
   wind up changing in the future).

 * XE_GT1 was only being used to set XE_MAX_TILES_PER_DEVICE which makes
   no sense at all; even though the highest tile count we have on any
   device today (2 on PVC) happens to match the number of GTs that we
   can potentially have inside a tile (2: primary+media on non-PVC
   platforms), these counts are unrelated and should not be tied
   together like this.

Cleanup the places where these were used and drop the two defines so
that they don't get mis-used anywhere else going forward.
