Fixes for most video cards, ramdacs and clock generators
...
1. Actually place the correct clocks in the PVGA-based ICS90c64a (see sources).
2. Make sure the difference between 4bpp and 8bpp in the BT484/5 ramdac is actually seen and done.
3. Forgot the ATI panning flag for the plain Mach64GX cards.
4. Fix standard VGA graphics mode for Japanese text in the Mach32 so that it's rendered correctly (if bit 5 of ati 0xb0 and bit 0 of 0x4aee clock select are 0).
5. Normalize ET4000AX clocks.
6. ET4000W32 series: fix some hwcursor issues in win3.1/winos2 (in non-24bpp modes) as well as well as the chips' clocks. Cleanup of the modes too.
7. Video7 HT208 cards: Add the 7.04 HP OEM bios and implement the clocks according to its manual (HT208, below).
8. More fixes of the stalls caused by FIFO stuff in non-FIFO modes (S3 stuff).
9. Remove unused code in vid_svga.c (vga core layer)

Refresh rate and acceleration fixes and cleanups for displays.
...
1. Some fixes to the S3 refresh rates using the bt48x ramdac as well as 32bpp acceleration (actually pixtrans reads) fixes, which are actually one single dword rather than two words. (This fixes some graphical bugs in 32bpp mode using OS/2 Warp with the Elsa 928 drivers).
2. Add undocumented ports 0x82ec and 0x82ed, needed by the Elsa OS/2 928/805i cards to operate correctly and not getting stuck at a blank screen.
3. Workaround a read select register issue when reading back the accelerated height (0xbee8 index 0x0f bits 3-0 returning a non-height index, in this case, 0x0e) so that the height is not zeroed on writes after the first reads, allowing text and fonts to be displayed on OS/2 Warp 3's built-in S3 864 drivers in every bpp.
4. Don't run the mach8/32 specific clock if we're in plain VGA text mode.
5. Some cleanups to the et4000w32 chip series, including a clock (refresh rate) fix for OS/2's built-in drivers and the extended crtc parameters to be run only on graphics modes.
