MIPS: uasm: Remove needless ISA abstraction

We always either target MIPS32/MIPS64 or microMIPS, and always include
one & only one of uasm-mips.c or uasm-micromips.c. Therefore the
abstraction of the ISA in asm/uasm.h declaring functions for either ISA
is redundant & needless. Remove it to simplify the code.

This is largely the result of the following:

  :%s/ISAFUNC(\(.\{-}\))/\1/
