media: i2c: ov2659: Use clk_{prepare_enable,disable_unprepare}() to set xvclk on/off
On some platform(imx6q), xvclk might not switch on in advance,
also for power save purpose, xvclk should not be always on.
so, add clk_prepare_enable(), clk_disable_unprepare() in driver
side to set xvclk on/off at proper stage.
Add following changes:
- add 'struct clk *clk;' in 'struct ov2659 {}'
- enable xvclk in ov2659_power_on()
- disable xvclk in ov2659_power_off()
