ar71xx: add AVM FRITZ!WLAN Repeater 300E support

Specifications:
* SoC: AR7242 (Virian 400MHz)
* RAM: 64 MB DDR (W9751G6JB-25)
* Flash: 16MB SPI flash (S25FL129PIF)
* WiFi: AR9382 (2.4/5GHz) + 2x SE2595L
* LAN: 1x1000M (PEF7071V)

To install LEDE via EVA bootloader, a FTP connection need to be
established to 192.168.178.1 within the first seconds after power on:
