[LEDE-DEV] [PATCH] ramips: Add I2C driver to the default kernel config

[Rosen Penev]

I made a commit that added the RTC driver to the kernel config with
the intent that it would fix hctosys. Unfortunately while the RTC
driver is in there, it's connected through I2C, the driver for which
comes in module form and is thus loaded late. After this commit, it
works fine.
