Subject: [PATCH] ARM: dts: BCM5301X: Add basic DT for Phicomm K3

This router has BCM4709C0, 128MB NAND flash (MX30LF1G18AC-TI),
and 512MB memory, with 3 x LAN and 1 x WAN. WL chips are
BCM4366C0 x 2. The router has a small LCD and 3 capactive keys
driven by a PIC microcontroller, which is in turn wired to
UART1 of main board.

Everything except the LCD works. Hamster has activated LCD through
UART1, but further programming, i.e., a independent package, is
required to make sure its working properly.

Since the firmware of Broadcom 4366c0 has been provided by
openwrt.org, now its wireless is functional but limited. The
"official" firmware cannot work properly in some 5G Hz channel.
