set things up even if we're not the console

fix tpyo, now we can actually map registers from userland

simplify putchar() a bit, use 16bit accesses for fonts that are more than 8
pixels wide

remove sc_putchar - don't need it anymore

now that we know how, draw characters by hardware

get rid of the workarounds to draw rectangles less than 32 pixels wide
turns out the hardware applies a bit mask to all rectangle fills, and we
can turn the background transparent. With that we just

we don't need in the less than 32 pixels wide case.
Next step - figure out how to abuse that to draw characters
I bet Visualize EG works exactly the same way in that regard.

properly return status info in ioctl(WSDISPLAYIO_GVIDEO)

implement ioctl(GCID)

hyperfb(4): Nix trailing whitespace.

No functional change intended.

magic number reduction, NFC

do cursor position updated the way NGLE does - poke reg 28 and wait_fifo
instead of waiting for the whole thing to go idle

fix tpyo and properly limit what we can mmap()

hyperfb(4): Nix trailing whitespace, sprinkle KNF.

No functional change intended -- just whitespace (and comments).

use the blitter to draw small rectangles as well by abusing set/clear ops
and the plane mask

hand X a 24bit framebuffer if the hardware supports it

remove a bunch of #defines that have been moved to stireg.h

add cursor sprite support

we have a blitter - use it

first shot at a native driver for HCRX cards
this will give you a fully working wsdisplay in 8bit colour living in the
overlay planes, X/wsfb will also work.
No acceleration or cursor sprite support
