lcd: Let the board code show board-specific info

The information displayed when CONFIG_LCD_INFO is set is inherently
board-specific, so it should be done by the board code. The current code
dealing with this only handles two cases, and is already a horrible mess
of #ifdeffery.

Yes, this duplicates some code, but it also allows boards to print more
board-specific information; this used to be very difficult.
