ARM: imx6q: replace clk_register_clkdev with clock DT lookup
It really becomes an maintenance issue that every time a device needs to look up (clk_get) a clock we have to patch kernel clock file to call clk_register_clkdev for that clock. Since clock DT support which is meant to resolve clock lookup in device tree is in place, the patch moves imx6q client devices' clock lookup over to device tree, so that any new lookup to be added at later time can just get done in DT instead of kernel.
