MIPS: inst.h: Fix some instruction descriptions

Browse Source 
Fix the description of the microMIPS NOP16 encoding or MM_NOP16, which
is not equivalent to the MIPS16 NOP instruction.  This is 0x0c00 and
represents the microMIPS `MOVE16 $0, $0' operation, whereas MIPS16 NOP
is encoded as 0x6500, representing `MOVE $0, $16'.

Also fix a typo in `mm_fp0_format' description.
