[PATCH 7/7] mfd: exynos-lpass: Add runtime PM support

[Marek Szyprowski]

Convert exisitng lpass-suspend/resume callbacks into runtime PM callbacks.
This way Exynos LPASS driver will be ready for use with power domains
enabled. LPASS will be runtime resumed/suspended as a result of its child
devices runtime PM transitions.
