[LEDE-DEV] [PATCH] ramips: fix GPIOs for Ubiquiti EdgeRouter X-SFP

[Sven Roederer]

This adds the i2c-gpio and i2c-pca95xx module to the default kernel.
Even they are listed in the dependencies of the board, they are not
built and for this missing in the imagefile. This causes that the
accessed hardware is not avail.
