cf49686957 Accelerator fixes part 2: 8514/A. 
Mix patterns are drawn at the correct position now instead of backwards.
Better handling of subsys/subcntl side.
As usual, better handling of the VGA on/off passthrough.
Better handling of the accelerator pitch (TODO: need a way to properly identify 640x480x256 in the pitch side).

a77271cfa6 Accelerator fixes part 1: 
XGA: Fix crash when (S)VGA cards not selected as the primary display (e.g.: EGA, CGA. etc).
Better handling of the VGA on/off passthrough (vga_on variable).
MCA side: to avoid lfb issues, bit 0 of POS4 will be always enabled regardless of the ram size (most software uses the >16MB memory method).
Better handling of the BIOS ROM mapping and Memory Mapped I/O during the MCA PS/2 POST and resets, fixes 40 25 hang (once and for all).
Re-organized the ROM loading in ISA mode.

TC1995
247c5df801 ET4000w32/i (and non-i): Mouse cursor shape is now alright by being forced to be 128x128 and if the cursor regs (0xe2 and 0xe6) have a non-0 value in the non-i chip (or if on 15/16bpp, forcing it to 128x128 anyway). 
Also fixed are the blitter patterns in 8/15/16bpp modes by re-ordering (if it's the right term) the pixels of the Y pattern coordinates (code lines are from 1165 to 1183).
And properly implemented X/Y Count control routing blitters, fixes anything that uses software Bresenham and/or polygon stuff.

2a395efbc9 vid_ega: Fix address decoding for Odd/Even modes for the 4bpp gfx renderers 
This, combined with the Odd/Even fixes from a previous commit, gets the 64KB 640x350 2bpp modes working correctly.

77ba033fd9 vid_ega: Fix CCLK/2 rendering in 4bpp graphics modes 
Required for 64KB-variant 640x350 2bpp modes (BIOS modes 0x0F, 0x10).
This does need some address decoding fixes to break the 16K-word barrier, though - those are coming.
