hppa/summitfb(4): Nix trailing whitespace again.

(ab)use the image buffer as glyph cache, since on this thing we can set source
and destination buffer independently

Use KM_SLEEP in attach path code.

reshuffle summitfb_setup():
- remove magic number inits that are no longer magic
- annotate the remaining inits if we know the register names
- zero the attribute plane
while there, cull excessive calls to summitfb_setup()

clean up aroound sti_fetchfonts(), mke sure we call wsfont_init() nefore
trying to add s font to the system
while there, allow mmap()in the entire fb aperture, no sense in restricting it

Oops. Turn off debug.

KNF

Remove some unnecessary casts and parenthesis

hppa/summitfb(4): Nix trailing whitespace.

No functional change intended.

now that we can do ROPs, use them and enable all the lazy cursor update stuff

some updates:
- setup attributes for RGB8 in the image planes and 8I in the overlay
- explicitly select LUT 0 for the overlay so we don't depend on what STI sets
  anymore - now this should work on all FX cards
- expose 24bit framebuffer to X
- make sure we switch overlay transparency according to WSDISPLAY_SMODE
- remove unnecessary register writes when accessing the colour map
- no need to call summitfb_setup_fb() in summitfb_do_cursot() - that was for
  HCRX and friends
- support screen blanking

set the right cursor sprite colours, now that we know how

avoid console output between sti_init() and wsdisplay_cnattach()

do not zero the cursor position register on each colour map access, instead
do it when initializing fb access
-> no more disappearing cursor sprite

remove declaration of sti_unitoroman[] since it lives in stivar.h now

some udates:
- fetch the ROM font, convert it to ISO and hand it to wsfont so we can mimic
  firmware output should we feel like it
- set read mode to match write mode whenever we touch the latter

hppa/summitfb(4): Nix trailing whitespace again.

add support for alpha fonts and glyph cache, disabled by default since there
is guesswork involved
also, store bitmap fonts in video memory, mostly to show how to change colours
around

hppa/summitfb(4): Nix trailing whitespace.

No functional change intended.

reshuffle unknown register inits, move the ones identified

hppa/summitfb(4): Nix trailing whitespace.

Plus some other minor whitespace/comment cleanups.

some cleanup & optimization:
- don't write the pixel mask register for operations that don't use it
- track write mode, only wait if we change it
- always sync when switching in and out of fb mode ( for X... )
- drop sc_hwmode
... about 10% speedup and no more glitches when starting X

make sure we apply the pixel mask when drawing characters so we don't scribble
outside the character cell

now that we know how, use the blitter to:
- draw characters
- scroll
- rectangle fills
no ROP support yet, so the cursor is drawn using putchar
while there get rid of some unused cargo-culted goop from gftfb
MUCH faster now

CV: ----------------------------------------------------------------------

use summitreg.h

add hardware cursor support
while there remove debug goop, fix ioctl(GCID)

hppa/summitfb(4): Fix SUMMITFB_DEBUG build.

hppa/summitfb(4): KNF

No functional change intended.

beginnings of a driver for Visualize FX graphics cards
So far it does:
- work on my FX4
- use the 8bit overlay, in R3G3B2
- all drawing by software, clear screen by hw
- X works in 8bit with wsfb
