[PULL 16/22] macfb: add VMStateDescription fields for display type and VBL timer

[Mark Cave-Ayland]

These fields are required in the migration stream to restore macfb state
correctly.

Note this is a migration break, but since there are upcoming incompatible 
changes
for the q800 machine (and migration does not even succeed without these patches)
then this is not an issue.
