[PATCH v6 26/41] ARM: da8xx: add new USB PHY clock init using common clock framework

This adds the new USB PHY clock init in mach-davinci/usb-da8xx.c using
the new common clock framework drivers.

The #ifdefs are needed to prevent compile errors until the entire
ARCH_DAVINCI is converted.

v6 changes:
- rename stuff to match changes in "clk: davinci: New driver for TI DA8XX USB
   PHY clocks"
- take advantage of syscon lookup changes in "mfd: syscon: Add syscon_register()
   function"
