Russell King 0a0300dc8c ARM: Consolidate clks_register() and similar
Most machine classes want some way to register a block of clk_lookup
structures, and most do it by implementing a clks_register() type
function which walks an array, or by open-coding a loop.

Consolidate all this into clkdev_add_table().
