[PATCH] Add support for Loongson-3A.

[Stefan Tauner]

Also be less restrictive regarding Loongson 2, because these strings seem
to be rather volatile:

Let's pretend I know what I am doing here... if I read the chinese
data sheets correctly then Loongson-3B has moved to use SPI primarily
for its firmware but there is always a chipset attached too...
In any case I would rather not touch it yet. 3A OTOH seems to be
more similar to Loongson-2 so this might actually work.

This patch applies w/o conflicts to r1565 and later.
