MIPS: CPS: Fix r1 .set mt assembler warning
MIPS CPS has a build warning on kernels configured for MIPS32R1 or
MIPS64R1, due to the use of .set mt without a prior .set mips{32,64}r2:
arch/mips/kernel/cps-vec.S Assembler messages:
arch/mips/kernel/cps-vec.S:238: Warning: the `mt' extension requires MIPS32 revision 2 or greater
Add .set MIPS_ISA_LEVEL_RAW before .set mt to silence the warning.
Fixes: 245a7868d2f2 ("MIPS: smp-cps: rework core/VPE initialisation")
