Create simple omap_devices for the main processors and busses. This is required to support the forth-coming device-based OPP approach, where OPPs are managed and tracked at the device level. Also, move these common PM init functions into a common_pm_init call that is called as a device_initcall(). The PM init is done at this level to ensure that the driver core is initialized before initialized. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> [paul@pwsan.com: sparse warnings cleaned up; newly-created functions moved from mach-omap2/io.c to mach-omap2/pm.c; newly-created functions renamed to start with "omap2" rather than "omap"] Signed-off-by: Paul Walmsley <paul@pwsan.com>
