I mean "load via the normal device model". For example the AC97
drivers need to be loadable by the codec id. There's no entry in
scripts/mod/file2alias.c for dynamically loading the modules.  They
don't have an id_table.

My AC97 driver is detecting the codec id and printing it before trying
to access the codec driver. I can convert that to a load_module() call
when the drivers are ready.

The core needs to detect if a specific codec id can't be supported to
fall back to the generic AC97 driver.
