Reviewing the MIPS code, ASE after ASE.
Time for MT ASE.

- Introduce/use ase_mt_available() helper to check
  if MT ASE is present
- Avoid setting MT specific registers if MT ASE is absent

Philippe Mathieu-Daudé (5):
  target/mips: Remove mips_def_t unused argument from mvp_init()
  target/mips: Introduce ase_mt_available() helper
  target/mips: Do not initialize MT registers if MT ASE absent
  hw/mips/malta: Do not initialize MT registers if MT ASE absent
  hw/mips/malta: Rewrite CP0_MVPConf0 access using deposit()

Thanks, applied to mips-next.
