port80: Add a config to avoid logging port80 codes
Add a config item to disable logging all of the port80
history buffer as each code is received.
Individual codes can still be logged as they are received when
enabled via the console command 'port80 intprint' or
using the CONFIG_PORT80_PRINT_IN_INT config item.
This reduces the overhead at AP startup
on the logging. It has been observed on the ITE81302 that
logging the port80 codes causes significant overhead that
may lead to watchdog timeouts.
The port80 code history is still available via the 'port80'
EC console command.
