[PATCH v4 9/9] arm: dts: mt7623: add dts file for Bananapi R2 (BPI-R2) board

From: Sean Wang <sean.wang at mediatek.com>
Add support for the Bananapi R2 (BPI-R2) development board from
BIPAI KEJI. Detailed hardware information for BPI-R2 which could be
found on http://www.banana-pi.org/r2.html
The patch currently only adds Mediatek GMAC, MT7530 Switch, the crypto
engine, USB, IR, I2S, I2C, UART, SPI, PWM, GPIO keys, GPIO LEDs and
PMIC LEDs. As to the other missing hardware and peripherals, they would
be added and integrated continuously.
