[PATCH v2 06/22] drm/xe/xe3p_lpm: Handle MCR steering

[Lucas De Marchi <lucas.demarchi@intel.com>]

From: Matt Roper <matthew.d.roper@intel.com>

Xe3p_LPM's MCR steering has the same ranges and behavior as Xe3_LPM.
However one register range that was reserved on Xe3_LPM has now become a
unicast range (0x384200-0x38427F), so we need to stop consolidating the
adjacent MCR ranges into a single table entry in the table.  With this
change to the Xe3_LPM table, we can continue to use the same table for
both IP families.

While we're touching this table, take the opportunity to fix a
whitespace mistake and clarify that one of the other consolidated range
entries includes a reserved range.
