A framebuffer driver for HP's Visualize-FX series of cards. The aim is
to support all FX2 - FX10 types but currently only FX5 is tested.

This driver is an updated version of the one which Sven Schnelle
originally posted here:
https://lore.kernel.org/all/20211031195347.13754-1-svens@stackframe.org/

Additional changes:
- added support for 32bpp
- added copyarea to bitblt from screen to screen
- allows screen sizes of up to 1920x1600 pixel
- lots of minor fixes (and probably new bugs)

This driver is still under development, nevertheless it would be great if
people could test.
This driver will not work on FX-10 cards yet.
