[PATCH 1/2] ARM: imx: unset pllv3 BYPASS and POWER sequentially

[jiada_wang at mentor.com]

From: Dirk Behme <dirk.behme at de.bosch.com>

Currently, POWER and BYPASS bits are set up in a single write to pllv3
register. With commit 43c9b9e8a4c6 ("ARM: imx: set up pllv3 POWER and
BYPASS sequentially") this has been changed in the prepare() function.
Do the same for the unprepare().
