commit cbbda6e7 upstream.

BMIPS5000 have a PrID value of 0x5A00 and BMIPS5200 have a PrID value of
0x5B00, which, masked with 0x5A00, returns 0x5A00. Update all conditionals on
the PrID to cover both variants since we are going to need this to enable
BMIPS5200 SMP. The existing check, masking with 0xFF00 would not cover
BMIPS5200 at all.

Fixes: 68e6a783 ("MIPS: BMIPS: Add PRId for BMIPS5200 (Whirlwind)")
Fixes: 6465460c ("MIPS: BMIPS: change compile time checks to runtime checks")
