MIPS: tlb: Set the EHINV bit for TLBINVF cores when invalidating the TLB

For MIPS32R3 supported cores, the EHINV bit needs to be set when
invalidating the TLB. This is necessary because the legacy software
method of representing an invalid TLB entry using an unmapped address
value is not guaranteed to work.
