The single-operand form of tlbie used to be accepted as the second
operand (L) being implicitly 0. Newer binutils reject this.

Change remaining single-op tlbie instructions to have explicit 0
second argument.

Do old(er) binutils accept the two operand version?

They should going back to 2002, but now I dig further into it, the problem
is
my cross compiler that is not setting the cpu / ISA version correctly. So
powerpc32 CPUs with current binutils tlbie second parameter is still
optional
AFAIKS.

So this patch is not required.

Thanks,
