MIPS: Implement microMIPS MT ASE helpers
Implement various microMIPS MT ASE helpers accroading to:
MIPS® Architecture for Programmers
Volume IV-f: The MIPS® MT Module for the microMIPS32™ Architecture
Fixes build error:
{standard input}:2616: Error: branch to a symbol in another ISA mode
This make MT ASE available on microMIPS as well.
Boot tested on M5150 with microMIPS enabled on M5150.
