MIPS: fix read_msa_* & write_msa_* functions on non-MSA toolchains
Commit d96cc3d1ec5d "MIPS: Add microMIPS MSA support." attempted to use
the value of a macro within an inline asm statement but instead emitted
a comment leading to the cfcmsa & ctcmsa instructions being omitted. Fix
that by passing CFC_MSA_INSN & CTC_MSA_INSN as arguments to the asm
statements.
