iop32x: gpio breakage after "instantiate GPIO from platform device"

[Arnd Bergmann]

Commit 7b85b867b9904 "ARM: plat-iop: instantiate GPIO from platform
device" nicely cleaned up the gpio register access for iop, but
forgot one board that directly pokes into the gpio registers
to do a system reset.

That board no longer compiles, and this patch just disables
the code in question to work around it so I can locally build
randconfig again, but it needs to be fixed properly.
