MIPS: Remove remnants of 48-bit microMIPS instruction support

The POOL48A major opcode was defined in early revisions of the 64-bit
microMIPS ISA, has never been implemented, and was removed before the
64-bit microMIPS ISA specification[1] has been finalized.

This complements commit a6c7053929dd ("MIPS/opcodes: Remove microMIPS
48-bit LI instruction").
