We have two knobs to flush for write booster, i.e.
fWriteBoosterBufferFlushDuringHibernate and fWriteBoosterBufferFlushEn.
However, many product makers uses only fWriteBoosterBufferFlushDuringHibernate,
because this can reportedly cover most scenarios and
there have been some reports that flush by fWriteBoosterBufferFlushEn
could lead to raise power consumption thanks to unexpected internal
operations. So we need a way to enable or disable fWriteBoosterEn
operations. For those case, this quirk will allow to avoid manual flush
