Patch to add the missing devices.

Hi,

at the restructuring of the /sys/arm64/conf directory

https://cgit.freebsd.org/src/commit/sys/arm64/conf/GENERIC?id=0f2c633164a6af70db8a8ecf4f70f61d241e7529

D30474

the GENERIC configuration lost its ability to detect the ethernet interface
on some RPi models at least.

I traced it down to missing devices smsc and dwcotg.

As dwcotg seems not to be build as a kernel module,
kldload if_smsc does not bring the ethernet interface back.

My suggested patch contains the minimal additions for the std.broadcom file
as I found this regression on a RPi.

Regards, Ralf

(In reply to commit-hook from comment #1)
Just booted a kernel with the commited patch.
Fixes the regression as well, as expected.
Thank you.

Ralf
