Move the existing clock code in mach-msm to the common clock framework. We lose our capability to set the rate of and enable a clock through debugfs. This is ok though because the debugfs features are mainly used for testing and development of new clock code. To maintain compatibility with the original MSM clock code we make a wrapper for clk_reset() that calls the struct msm_clk specific reset function. This is necessary for the usb and sdcc devices on MSM until a better suited API is made available.
