arm/machine: add zephyr machine conf for microbit

Browse Source 
Zephyr supports QEMU based machine for Cortex M0 (qemu-cortex-m0).  This
is actually using the BBC Microbit v1 machine in QEMU.  Use this more
accurate name for the machine conf.  This enables us to verify m0
tunings.

NOTE: qemu-cortex-m0's zephyr config has SRAM too small to run
zephyr-kernel-test-all, but can run zephyr-philosophers and
zephyr-kernel-test-sleep (and possibly others).
