MIPS: microMIPS: Fix macro naming in micro-assembler.
The macros did not properly take into account the ISA that the kernel was being compiled with. A classic MIPS kernel will have the standard 'uasm_i_##op' macro functions with 'MM_uasm_i_##op' macro functions for the microMIPS version. A pure microMIPS kernel will have the standard macros with 'CL_uasm_i_##op' macro functions for the classic version. Signed-off-by: Steven J. Hill <Steven.Hill@imgtec.com>
