clk: sunxi: Add VE (Video Engine) module clock driver for sun[457]i
The video engine has its own special module clock, consisting of a clock
gate, configurable dividers, and a reset control.
On later (sun[68]i) families, the reset control is moved out of this
piece of hardware and grouped with reset controls of other peripherals.
