ath79: fix support for Buffalo WZR-HP-G450H and split to dts/dtsi
There are many parts that are incorrect or missing in the current code for Buffalo WZR-HP-G450H in ath79, so its support is broken. I fixed that issues and split to dts/dtsi files to add support for Buffalo BHR-4GRV. And WZR-450HP has the same hardware as WZR-HP-G450H, so I change the device name to "WZR-HP-G450H/WZR-450HP". Specification: - Atheros AR7242 - 64 MB of RAM - 32 MB of Flash - 2x 16 MB SPI-NOR flash - 3T3R 2.4 GHz wifi - SoC internal - 5x 10/100/1000 Mbps Ethernet - 6x LEDs, 5x keys - 1x USB 2.0 Type-A - UART header on PCB - JP1: Vcc, GND, TX, RX from reset button side Flash instruction using factory image: 1. Boot the WZR-HP-G450H (or WZR-450HP) normaly and connect the computer to its LAN port 2. Access to "http://192.168.11.1/cgi-bin/cgi?req=frm&frm=py-db/firmup.html" with user "bufpy" and password "otdpopy" 3. Select the OpenWrt factory image and click "OK" button to perform firmware update 4. Wait ~200 seconds to complete flashing Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com>v19.07.3_mercusys_ac12_duma
