3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fabio Baltieri <fabio.baltieri@xxxxxxxxxx>
commit 99d17cfa3bbc6f4edb175f819af59c6b9e245e82 upstream.
This patch converts the module to use clk_prepare_enable and
clk_disable_unprepare variants as required by common clock framework.
Without this the system crash during probe function.
