ramips: fix DCH-M225 support

Browse Source 
Setting the pins of the UARTF group to GPIO+I2S at the time the I2C
driver loads is to late for the wps GPIO button.

The gpio-keys driver fails to load since the pin used by the wps button
is not yet set to GPIO. The wps button with the rfkill keycode is
essential for this wireless only board.

Add the missing sound and I2C kernel modules corresponding to the
device nodes.
