[PATCH] fbdev: omapfb: delete check_required_callbacks()

Commit 561eb9d09a93 ("fbdev: omap/lcd: Make callbacks optional") made
panel callbacks optional but forgot to update check_required_callbacks().
As a result many (all?) OMAP systems using omapfb will crash at boot.
Fix by deleting the whole function.
