  target-mips: fix semihosting for microMIPS R6

In semihosting mode the SDBBP 1 instructions should trigger UHI syscall,
but in QEMU this does not happen for recently added microMIPS R6.
Consequently bare metal microMIPS R6 programs supporting UHI will not run.

  Log Message:
  -----------
  target-mips: Copy restrictions from ext/ins to dext/dins

The checks in dins is required to avoid triggering an assertion
in tcg_gen_deposit_tl.  The check in dext is just for completeness.
Fold the other D cases in via fallthru.

In this case the errant dins appears to be data, not code, as
translation failed to stop after a break insn.
