Subject: [PATCH] mips: ralink: allow zboot

Architecturally, there's nothing preventing compressed images from
working.  Bootloaders built with support for the various compression
methods can decompress and run the kernel.  In practice, many
bootloaders do not support compressed images, but kernels for those
boards should just not be compressed.

Tested on an MT7688 with U-Boot doing LZMA decompression of uImage.
