p9_sbe_npll_setup -- update SS enablement for p9a
Axone has two spread PLLs that can individually synchronized, so the
TOD timer facility grew two enable bits. Set both of them to
synchronize both PLLs at the same time. The enable bits are don't
care on Nimbus/Cumulus so the procedure will still work the same
way there.
Check only the status of one PLL, knowing that if both are enabled,
either both or none will get started by the TOD. This maintains
Nimbus/Cumulus compatibility on the checking part.
