When support for Routerboard 911G was introduced, Routerboad 912UAG
device tree was used as a base, and the common part. This led to use of
40MHz as the reference clock frequency for both [1], while RB911G uses 25MHz
crystal on the board, causing heavy system clock drift.
Split the definition, and set the reference clock frequency for RB911G
back to 25MHz.

This is a stripped-down version of RB912UAG-(2,5)HPnD, without USB,
miniPCIe and SIM sockets.
This board has been supported in the ar71xx.
Add support based on RB912UAG board, by splitting out the common part to
.dtsi, and creating separate device tree for the stripped-down version.
