ARM: AM33xx: Add support for Clock Synthesizer

The CDCE913 and CDCEL913 devices are modular PLL-based, low cost,
high performance , programmable clock synthesizers. They generate
upto 3 output clocks from a single input frequency. Each output can
be programmed for any clock-frequency.

Adding support for the same.
