OMAP2+ / PM: move runtime PM implementation to use device power domains

Browse Source 
In commit 7538e3db6e (PM: add support
for device power domains) a better way for handling platform-specific
power hooks was introduced.

Rather than using the platform_bus dev_pm_ops overrides
(platform_bus_set_pm_ops()), this patch moves the OMAP runtime PM
implementation over to using device power domains.

Since OMAP is the only user of platform_bus_set_pm_ops(), that
interface can be removed (and will be in a forthcoming patch.)

[rjw: Rebased on top of a previous change modifying the handling of
 power domains by the PM core so that power domain callbacks take
 precendence over subsystem-level PM callbacks.]
