Aidan MacDonald 6a6c6083fa x1000: bootloader: fix Linux self-extracting kernel boot
Basically, there's longstanding bug in Linux with self-extracting
kernels on MIPS which just happened to manifest now on the M3K as
a hang on boot. The fix is applied to the M3K and Q1 since they
both use this type of kernel image.
