bus/nubus: More improvements to SuperMac Spectrum video cards.

Factored CRTC and shift register out of Spectrum/8 and added to Spectrum
PDQ.  Fixes video mode selection and resolution for Spectrum PDQ.

Implemented vertical interrupt position, stride, line offset and clock
source registers for Spectrum PDQ.  Added a hack to work around line end
control not being understood.  Also added save state support.

Slightly modernised the Macintosh Display Card (JMFB) device code.

Initialised some driver state class members that were causing System 7
to fail to see files. [Ivan Vangelista]
