Existing gpio-gate-clock driver acts like a simple GPIO switch without any
effect on gated clock. Add actual clock actions into enable/disable ops and
implement get_rate op by passing gated clock if it is enabled.

Add driver which implements GPIO-controlled clock. The GPIO is used
as a gate to enable/disable the clock. This matches linux clk-gpio.c
driver, however this does not implement the GPIO mux part, which in
U-Boot DM would be better fit in separate driver.
