Simplified configuration

I've moved SUPPORT_EEPROM into boards.h
because that seemed simplest.

I've removed a bit of logic related to serial
ports, because we now just listen on both if there
is more than one, using PRIMARY_SERIAL_PORT and
SECONDARY_SERIAL_PORT in boards.h.

I've deleted the `picohw` environment because it's no longer necessary.
