Subject: [PATCH] mips: Remove default endiannes

Currently, trying to build ci20_mmc fails on little-endian
toolchains. The problem seems to be that some targets don't
have CONFIG_SYS_LITTLE_ENDIAN properly set, and therefore
the default -EB switch is selected.

Let's get rid of the default switch entirely, and fix this problem.
While this may be a hack, it is a quick solution until
U-Boot gets CI20 proper support.
