Cover-letter:
Add Qemu tests for MIPS Malta machine

The currently used qemu_mips target respectively the Qemu
generic MIPS machine is marked as deprecated by Qemu. One should
use the MIPS Malta machine. Also the qemu_mips target only exists
in U-Boot, the Linux support was removed centuries ago. Thus we
should deprecated and remove the qemu_mips target eventually.
The first step would be to move the MIPS specific Qemu CI tests to
the Malta targets which also covers all 32/64 bit and Little/Big
Endian variants.

Successful CI runs on Gitlab, Travis CI and Azure:
