[PATCH v4 2/2] drm/xe/pcode: match argument naming with PCODE_DATAx

["Michał Grzelak" <michal.grzelak@intel.com>]

Variable naming of val and val1 should match register macro naming.

For xe, register macro naming of PCODE_DATA0 and PCODE_DATA1 is already
synced with register name. Nevertheless there are still functions
declaring val and val1. Rename val into val0 in functions declaring val1
in xe.

v4->v5
- split i915 changes from xe (Jani)

v3->v4
- apply the rename to the read()'s signature as well (Sashiko)

v2->v3
- resolve conflict from rebase

v1->v2
- rebase onto drm-tip (Jani)

Bspec: 19978, 19979
