[ARM] clkdev: fix clock matching The old matching algorithm was too fuzzy, causing false positives. For example, when asked for device D connection C1 and we only find device D connection C2, we return that as a valid match despite the connection names being different. Change the algorithm such that: An entry with a NULL ID is assumed to be a wildcard. If an entry has a device ID, it must match If an entry has a connection ID, it must match However, we maintain the order of precidence while still only doing a single pass over all entries: dev+con > dev only > con only.

ARM: 5979/1: CLKDEV: return from clk_find as soon as we get maching clk clk_find function looks for clock with matching dev_id and con_id. We should return from clk_find as soon as we get a clock with matching dev_id and con_id. This can be done by comparing variable "match" with 3.

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().
