Similar to the x86_64/pc test, it boots a Linux kernel on a raspi2
board and verify the serial is working.

The kernel image and DeviceTree blob are built by the Raspbian
project (based on Debian):
https://www.raspbian.org/RaspbianImages
as recommended by the Raspberry Pi project:
https://www.raspberrypi.org/downloads/raspbian/

If ARM is a target being built, "make check-acceptance" will
automatically include this test by the use of the "arch:arm" tags.

Alternatively, this test can be run using:

    $ avocado run -t arch:arm tests/acceptance
    $ avocado run -t machine:raspi2 tests/acceptance
