GDSCs (Global Distributed Switch Controllers) are responsible for
safely collapsing and restoring power to peripherals in the SoC.
These are best modelled as power domains using genpd and given
the registers are scattered throughout the clock controller register
space, its best to have the support added through the clock driver.

This patch adds support for the global clock controller found on the MSM8916
based devices. It allows the various device drivers to probe and control
their clocks and resets.

Add a driver for the global clock controller found on IPQ8064 based
platforms. This should allow most non-multimedia device drivers to probe
and control their clocks.
This is currently missing clocks for USB HSIC and networking devices.

The APQ8064 and MSM8960 share a significant amount of clock data and
code between the two SoCs. Rather than duplicating the data we just add
support for a unqiue APQ8064 clock table into the MSM8960 code.
For now add just enough clocks to get a basic serial port going on an
APQ8064 device.

Reset controllers and clock controllers are combined into one IP
block on Qualcomm chipsets. Usually a reset signal is associated
with each clock branch but sometimes a reset signal is associated
with a handful of clocks. Either way the register interface is
the same; set a bit to assert a reset and clear a bit to deassert
a reset. Add support for these types of resets signals.

Add a clock type that associates a regmap pointer and some
enable/disable bits with a clk_hw struct. This will be the struct
that a hw specific implementation wraps if it wants to use the
regmap helper functions.
