Olof Johansson 0065198e67 PM changes for am335x and am437x 
This series adds support for am437x RTC-only mode in suspend. In the
 RTC-only mode suspend, everything is shut down except the RTC. This
 makes the power consumption very low for suspend mode.
 
 To support RTC-only mode, we need to export omap_rtc_power_off_program()
 from the rtc driver and improve PM code to save and restore the wkup
 domain context. As RTC-only mode depends on the device being wired
 properly for things like memory, we need to also check for the machine
 type before we allow it. We also need to run DDR3 hardware leveling on
 resume.
 
 Note that there is a trivial merge conflict between the RTC branch
 and these changes where the RTC branch makes tm2bcd() a void function
 and the error handling parts can be just dropped.
