wifi: mt76: mt792x: pick the SAR table layout from the table itself
The SAR power tables are parsed with a version byte from a different
ACPI table, never their own.
Some firmware declares version 1 and ships version 2 tables. The
entries then start a byte early, and the 6 GHz limits the table
carries are dropped, because the older layout has no room for them.
ASUS GA503RM, MTCL declares v1:
MTGS 28 bytes v1: (28-6) % 5 = 2, no fit v2: 3 tables
MTDS 19 bytes v1: (19-6) % 6 = 1, no fit v2: 1 table
The layouts accept disjoint lengths, so take whichever one fits and
keep it per table.
