ramips: add Edimax RG21S

SoC:    MediaTek MT7621AT dual-core @ 880MHz
RAM:    256M (Nanya NT5CC128M)
FLASH:    16MB (Macronix MX25L12835F)
WiFi:    - 2.4GHz MediaTek MT7615N bgn
    - 5GHz MediaTek MT7615N nac
Switch: SoC integrated Gigabit Switch (4 x LAN, 1 x WAN)
USB:    No
BTN:    Reset, WPS
LED:    4 red LEDs, indistinguishable when casing closed
UART:     UART is present as Pads marked J1 on the PCB.
    3.3V - RX - GND - TX / 57600-8N1
    3.3V is the square pad

Installation
------------
Update the factory image via the OEM web-interface
(by default:http://192.168.1.1)
The sysupgrade image can be installed via TFTP from
the U-Boot bootloader. Connect ethernet port 2.

v3: Update to DEVICE_VENDOR / DEVICE_MODEL in mt7621.mk
    renamed .dts according to new conventions
    Removed memory node from .dts
    Correct image size
    Whitespace fixes
v4: Added wifi0/1 labels to wifi nodes
    Model name corrected in dts
    Comments removed from .dts
v5: Corrected MT7615N PCI IDs
    Unnecessary kernel-modules removed from image
