Modify the sstfb (Voodoo1/2) driver:
- fix a memleak when removing the sstfb module
- fix sstfb to use the fbdev default videomode database
- add module option "mode_option" to set initial screen mode
- add sysfs-interface to turn VGA-passthrough on/off via
/sys/class/graphics/fbX/vgapass
- remove old debug functions from ioctl interface

The undocumented register BIOS uses for saving f_CNT seems to only be
mapped to I/O space while all the other HPT3xx regs are dual-mapped. Looks
like another HighPoint's dirty trick. With this patch, the deadly kernel
oops on the cards having the modern HighPoint BIOSes is now at last gone!

Fix the broken hotswap code: on HPT37x it caused RESET- to glitch when
tristating the bus (the MISC control 3/6 and soft control 2 need to be written
to in the certain order), and for HPT36x the obsolete HDIO_TRISTATE_HWIF
ioctl() handler was called instead which treated the state argument wrong.
Also, get rid of the soft control reg. 1 wtite to enable IDE interrupt --
this is done in init_hpt37x() already...

Save some space on the timing tables by introducing the separate transfer mode
table in which the mode lookup is done to get the index into the timing table
itself. Get rid of the rest of the obsolete/duplicate tables and use one set
of tables for the whole HPT37x chip family like the HighPoint open-source
drivers do. Documnent the different timing register layout for the HPT36x
chip family (this is my guesswork based on the timing values).
Have been tested and works fine on HPT370/302/371N.

Fix/remove bad/unused timing tables: HPT370/A 66 MHz tables weren't really
needed (the chips are not UltraATA/133 capable and shouldn't support 66 MHz
PCI) and had many modes over- and underclocked, HPT372 33 MHz table was in
fact for 66 MHz and 50 MHz table missed UltraDMA mode 6, HPT374 33 MHz table
was really for 50 MHz... (Actually, HPT370/A 33 MHz tables also have issues.
e.g. HPT370 has PIO modes 0/1 overlocked.)
There's also no need in the separate HPT374 tables because HPT372 timings
should be the same (and those tables has UltraDMA mode 6 which HPT374 supports
depending on HPT374_ALLOW_ATA133_6 #define)...

Fix serious problems with the HPT372N clock turnaround code:
- the wrong ports were written to when called for the secondary channel;
- it didn't serialize access to the channels;
- turnaround shou;dn't be done on 66 MHz PCI;
- caching the clock mode per-channel caused it to get out of sync with the
actual register value.
Additionally, avoid calibrating PLL twice (for each channel) as the second try
results in a wrong PCI frequency and thus in the wrong timings.
Make the driver deal with HPT302N and HPT371N correctly -- the clocking and
(seemingly) a need for clock tunaround is the same as for HPT372N. HPT371/N
chips have only one, secondary channel, so avoid touching their "pure virtual"
primary channel, and disable it if the BIOS haven't done this already.
Also, while at it, disable UltraATA/133 for HPT372 by default -- 50 MHz DPLL
clock don't allow for this speed anyway. And remove the traces of the former
bad patch that wasn't even applicable to this version of driver.
Has been tested on HPT370/371N, unfortunately I don't have an instant access
to the other chips...
