Subject: [PATCH] base: power - use clk_prepare_enable and clk_prepare_disable
When PM runtime is enabled in DaVinci and the machine migrates to
common clk framework, the clk_enable() gets called without
clk_prepare(). This patch is to fix this issue so that PM run
time can inter work with common clk framework.
