v2 -> v1: enable the quirk in exynos

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

  ufs: exynos: enable UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL
