[RFC PATCH openbmc v3 2/8] runqemu: Add palmetto target

[Andrew Jeffery]

Example use:

    $ bitbake obmc-phosphor-image
    $ runqemu palmetto slirp

Specifying slirp avoids needing root to configure network, which won't
work (yet). The palmetto-bmc machine currently only models the VIC and
timers from the AST2400, and adds a 8250 UART for a console, so there's
not much interesting to play with in terms of hardware support. But, we
can now boot the one kernel both on the hardware and in QEMU.
