clk: prima2: enable dt-binding clkdev mapping
this patche deletes hard code that registers clkdev by things like: clk_register_clkdev(clk, NULL, "b0030000.nand"); clk_register_clkdev(clk, NULL, "b0040000.audio"); clk_register_clkdev(clk, NULL, "b0080000.usp"); prima2 clock controller becomes a clock provider and every dt node just declares its clock sources by dt prop. it also makes us easier to extend this driver to support both prima2 and marco as marco has different address mapping with prima2.

* Clock bindings for CSR SiRFprimaII
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be "sirf,prima2-clkc"
|
||||
- reg: Address and length of the register set
|
||||
- interrupts: Should contain clock controller 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 prima2
|
||||
clocks and IDs.
