[U-Boot] sunxi: support NanoPi Neo2

Hi,

this diff adds basic support for the NanoPi Neo2.  It's based on the
old NanoPi Neo support and the recent commit of the OrangePi PC2
support.  I'm not sure it's 100% correct, but it seems to be a good
start to me and makes the machine boot.  Tested with Andre's SPL FIT
patchset.
