Not easily.

The existing callers of smc91c111_init() differ. Some (e.g. mainstone)
just create the device unconditionally, ignoring --nodefaults. Others
(e.g. integratorcp) are better behaved and do it only if a
configuration exists. (Citation of existing patch reinstated below)

And even if we wanted to convert the well-behaved ones to use
qemu_create_nic_device() directly, we'd still have to explicitly set up
the base address and IRQ, which smc91c111_init() currently does for us.

Some callers instantiate the device unconditionally, others will do so only
if there is a NICInfo to go with it. This appears to be fairly random, but
preserve the existing behaviour for now.

Wouldn't it be possible to use qemu_create_nic_device() here, too?

Anyway:
