DDR3A/B, ARM and PA PLL controllers have clkod register bits for
configuring postdiv values. So use it instead of using fixed
post dividers for these pll controllers. Assume that if fixed-postdiv
attribute is not present, use clkod register value for pistdiv.
Also update the Documentation of bindings to reflect the same.

Add the driver for the PLL IPs found on Keystone 2 devices. The PLL
IP typically has a multiplier, a divider and a post-divider. The PLL IPs like
ARMPLL, DDRPLL and PAPLL are controlled by the memory mapped register where
as the Main PLL is controlled by a PLL controller and memory map registers.
