Introduce a quirk to use CMB-like memory on older devices that have
an exposed BAR but do not advertise support for using CMBLOC and
CMBSIZE.

We'd like to use some of these older cards to test P2P memory.

I can't sat that I really like adding support for non-standardized
"features" (vs bugs) in the nvme driver.

I can live with this patch being dropped.
