[PATCH] drm/xe: Rename MCFG_MCR_SELECTOR to STEER_SEMAPHORE

[Nitin Gote]

The register at offset 0xfd0 was incorrectly named MCFG_MCR_SELECTOR,
likely copied from i915. According to the hardware specification (Bspec),
this register is actually called STEER_SEMAPHORE.

Rename the register definition and update its usage in xe_gt_mcr.c to
match the official hardware documentation.

No functional changes.

v2: Add Bspec reference (Tejas)

Bspec: 67113
