vga: vgastate fix
1) sets 'palette access disabled' during read from AR10.
This is usually documented as needed for access AR01-AR0F,
but on ARK Logic card it is needed for AR10 (otherwise read
returns some nonsence and save_vga_text() returns before do
anything).
2) do not restore AR10, because it was not changed during
3) remove modification of misc reg:
/* force graphics mode */
vga_w(state->vgabase, VGA_MIS_W, misc | 1);
as comment is misleading - LSB of misc reg does not set/reset graphics
mode, but set color/mono adresses of CRT and some other regs.
but these regs are not used during save/restore fonts.
(it worked even when (misc | 1) was replaced by (misc & ~1) ).
