omap: drop __initdata tags from static struct platform_device declarations
Pointers to statically declared platform device structures which are registered with platform_device_register() are then used during run time to access these structure members, for example from platform_uevent() and much more. Therefore, these structures should never be placed inside sections which are dropped after boot. Fix platform devices incorrectly tagged with __initdata which happen to exist inside OMAP sub-trees. This bug has exhibited itself on my ARM/OMAP1 based Amstrad Delta videophone after commit 6d3163ce86dd386b4f7bda80241d7fea2bc0bb1d, "mm: check if any page in a pageblock is reserved before marking it MIGRATE_RESERVE", resulting in reading from several /sys/device/platform/*/uevent files always ending up with segmentation faults.
