Heavily influenced by its Linux kernel counterpart. It's implemented on
top of recently added Samsung CCF clock framework API. For now only UART
leaf clocks are implemented, along with all preceding clocks in CMU_TOP
and CMU_PERI. The UART baud clock is required in the serial driver, to
get its rate for the consequent baud rate calculation.

Add a clock driver for Exynos7420 SoC. There are about 25 clock controller
blocks in Exynos7420 out of which support for topc, top0 and peric1 blocks
are added in this initial version of the driver.
