Some changes for the Bochs VBE 32k bank granularity feature.
...
- VBE enable register returns 32k granularity flag if enabled.
- VBE bank register returns 32k granularity flag if VBE_DISPI_GETCAPS is set.
- Defining new DISPI ID not necessary.
- TODO: update VGABIOS to use this feature.

Some changes for the Bochs VBE support.
...
- Limit VBE bank size to 64k as expected.

"noclear" bit is set.
- Prepared 32k bank granularity mode required for text output functions. Added
new VBE_DISPI_ID6 to indicate this capability. The default is still 64k.
