This is the third copy of OHCI platform setup code which is almost
the same except for the GPIO numbers. Can we attempt to consolidate
the GPIO case under drivers/usb/host/ohci-da8xx.c glue layer itself?
Of course, here should be a provision for non-GPIO based implementation
as well.

Sergei, any thoughts, comments?

Thanks,
Sekhar
