Benjamin Herrenschmidt 90c1e3c2fa powerpc/mm/radix: Update ERAT flushes when invalidating TLB 
Three tiny changes to the ERAT flushing logic: First don't make
it depend on DD1. It hasn't been decided yet but we might run
DD2 in a mode that also requires explicit flushes for performance
reasons so make it unconditional. We also add a missing isync, and
finally remove the flush from _tlbiel_va as it is only necessary
for congruence-class invalidations (PID, LPID and full TLB), not
targetted invalidations.

Fixes: 96ed1fe511 ("powerpc/mm/radix: Invalidate ERAT on tlbiel for POWER9 DD1")
