This is a crude mechanism to allow the pfc driver to
be registered through device tree. The mofication of this
is to provide a way for pfc gpios to be looked up by
device tree for devices which use pfc gpios.

More specifically, the motivation is to allow the registration
of the card-detect gpio for the Micro-SD SDHI slot of the KZM9G board.

I've just posted v2 of my PCF patches ("SH pin control and GPIO rework with OF 
support") that include OF support for GPIOs. This patch as well as patch 4/7 
and the gpio node in patch 7/7 and shouldn't be required anymore.

Thanks.
