[PATCH] ARM: dts: BCM5301X: Add DT for Buffalo WZR-1166DHP2

[SHIMAMOTO Takayoshi <takayoshi.shimamoto.360@gmail.com>]

Buffalo WZR-1166DHP2  wireless router with

 - BCM4708A0
 - 256MiB DDR2 SDRAM
 - 128MiB NAND flash
 - 2T2R 11ac/a/b/g/n Wi-Fi
 - 4x 10/100M ethernet switch

The hardware configuration is very similar to the WZR-1750DHP,
except for memory size and number of antennas.
