ARM: mx5: Replace clk_register_clkdev with clock DT lookup
Similarly as it was done for mx6q, use a DT lookup in order to make maintainance
task for the clock devices easier.

+* Clock bindings for Freescale i.MX5
+
+Required properties:
+- compatible: Should be "fsl,<soc>-ccm" , where <soc> can be imx51 or imx53
+- reg: Address and length of the register set
+- interrupts: Should contain CCM interrupt
+- #clock-cells: Should be <1>
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. The following is a full list of i.MX5
+clocks and IDs.
