Add maximum width and height options and set the default to 2560x1600

* The framebuffer mapping is now completely handled inside the

Although Intel's current spec[1] shows the OpRegion structure version
as being the top 16 bits of the field, Intel's Windows drivers
require the OpRegion structure version to be in the top 8 bits of
the field when not using a VGA BIOS (eg, NGI or GOP driver).
As the Linux i915 driver only checks that the version is >= 2,
there is no change in functionality there.
This change effectively matches Intel's implementation in TianoCore,
where the version is set to 0x0200 << 16.
