[Patch v6 2/7] clock: keystone-pllctrl: add bindings for keystone pll controller

The main pll controller used to drive theC66x CorePacs, the switch fabric, and a majority of the peripheral clocks (all but the ARM CorePacs, DDR3 and the NETCP modules) requires a PLL Controller to manage the various clock divisions, gating, and synchronization. Reviewed-by: Arnd Bergmann
