[PATCH 03/10] macfb: increase number of registers saved in MacfbState

[Mark Cave-Ayland]

The MacOS toolbox ROM accesses a number of addresses between 0x0 and 0x200 
during
initialisation and resolution changes. Whilst the function of many of these
registers is unknown, it is worth the minimal cost of saving these extra values 
as
part of migration to help future-proof the migration stream for the q800 machine
as it starts to stabilise.
