ARM: omap1: Fix new user of gpiochip_request_own_desc()

This fixes up a new user of gpiochip_request_own_desc() in
the AMS Delta board that appeared after the patch that was
applied recently.

There is one more AMS Delta related file where gpiod_request_own_desc() is 
called and the same fix is needed: arch/arm/mach-omap1/ams-delta-fiq.c.  With 
that fixed, you can add my

Both here and in ams-delta-fiq.c as well, gpiod_direction_input() is called 
soon after. That could be dropped if GPIOD_FLAGS_BIT_DIR_SET was used instead 
of 0.  I can take care of that and prepare a follow up patch if you prefer 
this one being kept as minimal as possible.

Thanks,
Janusz

I handled that in the original patch actually! :)

It's better if you send a separate patch as follow-up because
you know what you are doing, in contrast to me ... I just change
the function signature because I have to, it is always super scary
to patch other people's board files.

Sounds like you already applied, and no need to recommit,
so just for reference:
