[PATCH] auxdisplay: hd44780_common: Fix build error

[poeschel]

From: Lars Poeschel <poeschel@xxxxxxxxxxx>

When building the hd44780_common driver without a driver that actually
uses it like panel or hd44780 you got a build error, because
hd44780_common uses charlcd, but did not select it. It's users did
select it.
This is fixed now. hd4478_common now selects charlcd in Kconfig and
panel and hd44780 do not. They only select hd44780_common.
