usbdebug: Do not support logging from SMM

Letting SMI handler touch EHCI controller is an excellent source
of USB problems. Remove usbdebug entirely from SMM.

It may be possible to make usbdebug console work from SMM
after hard work and coordination with payloads and even
OS drivers. But we are not there.
