target-mips: add TLBINV support
For Standard TLB configuration (Config.MT=1): TLBINV invalidates a set of TLB entries based on ASID. The virtual address is ignored in the entry match. TLB entries which have their G bit set to 1 are not modified. TLBINVF causes all entries to be invalidated. Single TLB entry can be marked as invalid on TLB entry write by having EntryHi.EHINV set to 1. Signed-off-by: Leon Alrae <leon.alrae@imgtec.com> Reviewed-by: Yongbok Kim <yongbok.kim@imgtec.com>
