Add RCAN clock support to the R-Car generation 2 CPG driver. This clock gets
derived from the USB_EXTAL clock by dividing it by 6. The layout of RCANCKCR
register is close 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...

Ugh, forgot to clear the 'init.flags', so that it has some random value...
