clk: msm: osm: support PLL droop detector workaround

Add the architectural space register programming required to
workaround the droop detector and OSM PLL lock detect interaction.
In particular the workaround prevents the OSM sequence and FSMs
from waiting indefinitely for PLL lock in certain scenarios when
the droop detector is active. In addition, the new sequencer is
compatible with 3 levels of ACC settings, thus update the driver
to reflect this.
