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

Hi,

I believe the PCI-IDs of the devices in your device tree are wrong,
see below:

                             ^^^^^^^^^^^^^^
This looks wrong, MT7615N should have a different PCI ID (pci14c3,7615)

And here "pci14c3,7615" as well I reckon.

Dear Daniel,

thanks for spotting this. Indeed, the correct PCI device-id of the
MT7615N is 7615. 

Interestingly, the kernel module did not care. I'll submit a new v5
patch for the Edimax RG21S and also a new patch for the ASUS RT-AC85p
where I made the same mistake.
