clk: qcom: Add KPSS ACC/GCC driver
The ACC and GCC regions present in KPSSv1 contain registers to
control clocks and power to each Krait CPU and L2. For CPUfreq
purposes probe these devices and expose a mux clock that chooses
between PXO and PLL8.

Support for the high-frequency PLLs present on Qualcomm devices.
Say Y if you want to support CPU frequency scaling on devices
such as MSM8974, APQ8084, etc.
