c7c3f096eb auxdisplay: hd44780: Fix DT properties to include units of measurement
DT properties specifying physical properties should contain appropriate
suffices indicating the units of measurement.

Hence amend the HD44780 DT bindings to add "chars" suffixes to the
"display-height" and "display-width" properties, and update the driver
to parse them.

Fixes: d47d88361f ("auxdisplay: Add HD44780 Character LCD support")
