ramips: add linux zboot support

Browse Source 
linux-mips has zboot code which can create a self-extracting kernel
image.
This allows enabling kernel zboot support for ramips targets.

Subject: mips: ralink: enable zboot support
Some of these ralink devices come with an ancient u-boot which can't
extract LZMA properly when image gets too big.
Enable zboot support to get a self-extracting kernel instead of relying
on broken u-boot support.
