p9_setup_clock_term: Apply tweak bits, put oscswitches into reset
Put the oscswitches into reset by deasserting PGOOD before we turn on
clocks, to make sure they fall into a reliable defined state when we
assert PGOOD during p9_clock_test.
Update the set values of root controls with preliminary sys oscswitch
tweak bits; to be refined after full redundant oscillator bringup.
Refactor some code to make procedure more readable.
