OpenWrt support for D-Link DIR-1950 rev. A1

only without wifi and apparently just using one of both CPU cores, I wonder if it should be added with preliminary support anyways? (just like the ipTIME device)
not sure how useful that would be, i.e. this device does not seem quite widespread after all?

However, factory image encryption / decryption is solved by now, it's the same format as with DIR-1750, c.f. Bricked D-Link DIR-1750 - #11 by s_2
