Log Message:
4-line HD44780 LCD display support.  Work needed for the NetBSD toaster port.

The HD44780 actually doesn't support 4 lines, but the 4 line displays
use two chips, one for the top two lines and one for the bottom
two lines.  The chips share the databus, register-select, and write
signals but have separate enable signals.
