Fix ordering of VGA vs. plane disable
From the Intel 965 Programmer’s Reference Manual, volume 3,
chapter 2.2.2 "Mode Switch Programming Sequence".
The disable sequence should be:
- Disable planes (VGA or hires)
- Disable pipe
- Disable VGA display in 0x71400 bit 31
This patch implements that order plus waits for a vblank at the end.
Fixes bug #17756.
