AMBA has been done properly - bypassing the initial ID lookup with the
"arm,primecell-periphid" binding only prevent the HW from being
accessed when the DT is parsed.  At driver init time the peripheral ID
from the DT is checked against the list of AMBA IDs supported by the
driver and fails if a match is not found.

One can always force things with the "driver-override" sysfs property
but that's another story.
