There is no need to init .owner field.
Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"
This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

Sometimes we need to program PLLs with a fixed rate
configuration during driver probe. Doing this after we register
the PLLs with the clock framework causes the common clock
framework to assume the rate of the PLLs are 0. This causes all
sorts of problems for rate recalculations because the common
clock framework caches the rate once at registration time unless
a flag is set to always recalculate the rates.
Split the qcom_cc_probe() function into two pieces, map and
everything else, so that drivers which need to configure some
PLL rates or otherwise twiddle bits in the clock controller can
do so before registering clocks. This allows us to properly
detect the rates of PLLs that are programmed at boot.

The display clocks all source from dedicated phy PLLs within their
respective multimedia hardware block. Hook up these PLLs to the
display clocks with the appropriate parent mappings, clock flags,
and the appropriate clock ops. This should allow the display
clocks to work once the appropriate phy PLL driver registers their
PLL clocks.

We forgot to add the status bit for the PLLs and we were using
the wrong register and masks for configuration, leading to
unexpected PLL configurations. Fix this.

Most of the probe code is the same between all the different
clock controllers. Consolidate the code into a common.c file.
This makes changes to the common probe parts easier and reduces
chances for bugs.

Add a driver for the global clock controller found on MSM 8974
based platforms. This should allow most multimedia device drivers
to probe and control their clocks.
