[ARM] 5581/1: U300 clock updates
This adds a few default locks to the clocks (the clocks were used before the locks were initialized by code), then renames the clocks a bit to fit with the latest driver names (some changed during review). Lastly it moves the initialization of the clock debugfs entry to module_init() initcall level since the debugfs isn't up in core_initcall().
