USB: omap3: add platform init code for OHCI driver
Add platform init code for the OMAP3 OHCI driver. Also, configure padconf settings for OMAP3 depending on which port mode is used. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
