New templated DRM code. First pass at extracting out a lot of the common

    generic initialization code into template files that can be included
    and customized as required. Update mga, r128 and tdfx drivers to use
    the new template files. Gamma driver to follow.
Add initial mach64 kernel module using new template files. Should be enough
    to get the DRI to initialize, no support for DMA yet though. When I get
    a working Rage Pro card I will be able to continue...
