rtc: rtc-mv: Add support for clk to avoid lockups
commit 89c58c198b252f2bc20657fdd72a2aea788c435c upstream.
The Marvell RTC on Kirkwood makes use of the runit clock. Ensure the
driver clk_prepare_enable() this clock, otherwise there is a danger
the SoC will lockup when accessing RTC registers with the clock
disabled.
