[PULL 3/4] macfb: fix VRAM dirty memory region logging

[Laurent Vivier]

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

The macfb VRAM memory region was configured with coalescing rather than dirty
memory logging enabled, causing some areas of the screen not to redraw after
a full screen update.
