[PATCH] omap_cf: oops-on-suspend fix

Browse source 
Convert omap_cf into a platform_driver ...  this resolves oopsing during
suspend/resume.

Evidently folk haven't tried suspend/resume on an OSK (the main platform
for this driver) since September or so, which is when platform_device
learned about suspend_late()/resume_early() and stopped being able to
suspend/resume without a platform_driver.
