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.
