[PATCH v1 3/6] ARM: davinci: don't use static clk_lookup

In preparation of moving to the common clock framework, usage of static struct clk_lookup is removed. The common clock framework uses an opaque struct clk, so we won't be able to use static tables as was previously done. Each CPU family is given a new CPU-specific init_time function that
