ramips: add linux zboot support
linux-mips has zboot code which can create a self-extracting kernel image. This allows enabling kernel zboot support for ramips targets. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

+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.
