[PATCH] rtc: rtc-omap: Replace mdelay() with msleep() in omap_rtc_power_off()

[Jia-Ju Bai]

omap_rtc_power_off() is never called in atomic context.
It calls mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().

This is found by a static analysis tool named DCNS written by myself.
