powerpc/64s: Rename PPC_INVALIDATE_ERAT to PPC_ISA_3_0_INVALIDATE_ERAT
This makes it clear to the caller that it can only be used on POWER9 and later CPUs. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> [mpe: Use "ISA_3_0" rather than "ARCH_300"] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
