[PATCH V4 1/3] GPIO: MIPS: lantiq: move gpio-stp and gpio-ebu to the subsystem folder

[John Crispin]

Move the 2 drivers from arch/mips/lantiq/xway/ to the subsystem and make them
buildable.

The following 2 patches will convert the drivers to OF.

This patch is part of a series moving the mips/lantiq target to OF and clkdev
support. The patch, once Acked, should go upstream via Ralf's MIPS tree.
