[PATCH] power: reset: syscon-poweroff: Replace mdelay() with msleep() in syscon_poweroff()

[Jia-Ju Bai]

syscon_poweroff() 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.
