[PATCH v11 06/13] tests/qtest: Adjust and document query-cpu-model-expansion test for arm

[Fabiano Rosas]

We're about to move the 32-bit CPUs under CONFIG_TCG, so adjust the
query-cpu-model-expansion test to check against the cortex-a7, which
is already under CONFIG_TCG. That allows the next patch to contain
only code movement.

While here add comments clarifying what we're testing.
