[BRLTTY] BRLTTY in GRUB2

[Dave Mielke]

Would you consider adding const to the second argument (serial_port_config*) of 
serialPort->driver->configure(), or should I type-cast my way out of the
"assignment discards qualifiers" warning?

Is there a function to turn a grub_err_t into an error message for logging?
