[SeaBIOS] [PATCH 1/4] vgabios: Improve vgabios Kconfig menu.

[Kevin O'Connor]

Place driver types in a "choice" selection - only one driver type
makes sense.

Only prompt the user for PCI Vendor/Device ids if they wish to
override the default choices.  Otherwise, Kconfig wont know to use the
proper defaults when building autoconf.h.
