OMAP4 powerdomain: Support LOWPOWERSTATECHANGE for powerdomains
Some powerdomains in OMAP4 support a direct transition from one sleep state to another deeper sleep state without having to wakeup the powerdomain. This patch adds an api in the powerdomain framework to set the LOWPOWERSTATECHANGE bit in PWRSTCTRL register.
