vregion: Disable virtual regions on ACE 2.0 and earlier

The virtual memory heap does not work properly on MTL or LNL and
effectively the system from functioning due to virtual memory heap
allocations failing when the demand for module memory is high, like in
this test:

TPLG="/lib/firmware/intel/development/sof-lnl-nocodec.tplg" MODEL=LNLP_RVP_NOCODEC SOF_TEST_INTERVAL=10 ~/sof-test/test-case/multiple-pipeline.sh -f a -c 20 -l

Disable virtual memory heap for ACE 2.0 and earlier as quick remedy to
the problem. With proper tuning it may be possible to get VMH working
these platforms too.

Fixes: b3d0c47 (vregion: Add support for per pipeline/module virtual regions)
