[PATCH 4/7] clk: add prepare/unprepare helpers

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

barebox doesn't use interrupts, so it need not differentiate between a
possibly sleeping prepare/unprepare and an atomic enable/disable.

Provide a wrapper that just expands to the already existing functions to
simplify porting of Linux kernel drivers.
