Add the RCAN clock support to the R-Car generation 2 CPG driver. This clock
gets derived from the USB_EXTAL clock, dividing it by 6. The layout of the
RCANCKCR register is similar to those of the clocks supported by the 'clk-div6'
driver but has no divider field, and so can't be supported by that driver...
