powerpc/64s: Fix OPAL_CALL non-maskable interrupt reentrancy
OPAL_CALL uses SRR[01] with MSR_RI=1, which gets corrupted if there is an interleaving system reset or machine check interrupt. Use HSRR[01] instead, which does not require MSR_RI=0. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
