In downstream kernel we've standardized the clock consumer names that MSM device drivers use. Replace the uart specific clock names in this driver with the more standard 'core' and 'iface' names. Also simplify the code by assuming that clk_prepare_enable and clk_disable_unprepare() will properly check for NULL pointers (it will because MSM uses the common clock framework).
