[U-Boot] [PATCH 2/2] board/qemu-mips: add '-M mips' switch to the example usage command

[Gabor Juhos]

Using the example command from the README file does
not work as expected. qemu shows a text similar to
the one below and it hangs.

    $ qemu-system-mips -L . -nographic
    Could not open option rom 'pxe-pcnet.rom': No such file or directory
    qemu-system-mips: pci_add_option_rom: failed to find romfile "vgabios-cirrus.bin"
    qemu: terminating on signal 15 from pid 19726

This happens because qemu emulates a Malta board by
default if the machine type is not defined explicitely
on the command line.

For a working test, the '-M mips' switch is required:

    $ qemu-system-mips -M mips -L . -nographic
    Could not open option rom 'vgabios.bin': No such file or directory
