MIPS: mipsregs: Set proper ISA level for virt extensions

Browse Source 
c994a3ec7e ("MIPS: set mips32r5 for virt extensions") setted
some instructions in virt extensions to ISA level mips32r5.

However TLB related vz instructions was leftover, also this
shouldn't be done to a R5 or R6 kernel buid.

Reorg macros to set ISA level as needed when _ASM_SET_VIRT
is called.
