When CONFIG_ARC_USE_UNALIGNED_MEM_ACCESS=y, we also
need to add -Xunaligned option for mdb to enable unaligned
memory access feature for nsim.

In PR #26836, we switch nSIM from custom legacy ARC UART model
to ns16550 model, which will allow us to use zephyr images build for
nSIM on other platforms like HAPS, QEMU, etc...
In PR #27334, which introduce new board nsim_em7d_v22, has gone
parallel to the switch to dwuart, and is still using legacy model.
With wrong configuration, the uart for nsim_em7d_v22 has no output,
which cause all tests failure.

Typically we have ARC core configurations where Fast IRQs (FIRQ) are
enabled together with multiple register files and those we have covered
by testing. But FIRQ & single register bank we only happen to have on
the older EMSK v2.2.it might be a good idea to add a similar
configuration to nSIM "boards" so that we keep it tested regularly.
nsim_em7d_v22 configuration is similar with em_staterkit_em7d_v22,
both configed with FIRQ & single register bank.
