ramips: Ralink RT305x, support for Prolink PWH2004 (Abocom5205)

Browse Source 
The attached patch adds a preliminary support for Prolink PWH2004 board
(Ralink RT305x based). LAN and flash appear to work. However, the USB
port and WLAN I have not managed to activate properly yet, but that
problem appears to be present with other rt305x targets as well(?).
