mc6845.c: Rewritten to allow mid frame changes to the counter registers. This enables drivers to use advanced
split screen and scrolling effects using a regular mc6845. [Wilbert Pol]
Interface change:
The screen tag is no longer mandatory. If a screen tag is provided then the mc6845 device will resize
the screen and visible area based on the parameters set in the 6845 config and registers. If the screen
tag is not provided then the driver is supposed to be in charge of setting the proper screen configuration.
Warning: This breaks the relationship between the timing of a screen device and the signals generated
by the 6845.
