I'll add the lan78xx patches again.

The problem of patches no longer applying happens with other platforms
as well sometimes. Once we have kernel 4.19 support and 19.01 has been
branched, I would like to introduce a new target bcm283x and phase out
brcm2708. The idea is to use a vanilla kernel with as little patches as
possible,  and boot with vanilla u-boot. But to support the target at
all in 19.01, which will use kernel 4.14, I would like to push this to
master, and preferably sooner rather than later.
