James Hogan 42c86612d5 target/mips: Add an MMU mode for ERL
The segmentation control feature allows a legacy memory segment to
become unmapped uncached at error level (according to CP0_Status.ERL),
and in fact the user segment is already treated in this way by QEMU.

Add a new MMU mode for this state so that QEMU's mappings don't persist
between ERL=0 and ERL=1.
