[PATCH 2/7] clk: mvebu: move clk-cpu compatible strings into the clk-cpu driver

[Thomas Petazzoni]

Both the clk-core and clk-gating drivers define their compatible
string in their own .c file and provide an initialization function to
register the clock types. clk-cpu was not doing the same: it was
defining its compatible string directly in clk.c, and calling
of_clk_init() from here.

For consistency reasons, this patch moves the clk-cpu compatible
string in clk-cpu.c, and implements a proper mvebu_cpu_clk_init()
function like the other two clock drivers.
