        src/sys/dev/tc: cfb.c mfb.c sfb.c tfb.c xcfb.c

Log Message:
Add WSDISPLAYIO_GET_FBINFO support to most TURBOchannel framebuffers

This adds WSDISPLAYIO_GET_FBINFO to cfb, mfb, sfb, tfb and xcfb
TURBOchannel framebuffers as used by pmax and alpha

It does not add support to px and pxg (they handle ioctls in common
code in stic.c and more careful wiring is required)

These changes allow an Xswfb X server to use the framebuffer
directly, albeit without any special acceleration

A subsequent change will re-enable X server building on pmax, and
also hopefully switch alpha from Xorg 1.10 to 1.20
