add io ports for sleep (S3) support
related RHBZ: 688883
Sleep is supported by the following flow:
(G stands for Guest, D is the device, not the driver)
G: QXL_IO_ABOUT_TO_SLEEP
G: acpi reset
D: qxl_reset_handler (ignored)
G: QXL_IO_RETURNED_FROM_SLEEP
Thereby the spice-server and the driver never reset during sleep.
After an ABOUT there are three options:
RETURNED - normal case
vga io port written to - we already handle this by doing a qxl_soft_reset
QXL_IO_RESET - we call qxl_hard_reset which calls qxl_soft_reset
So to handle the two unmatched cases we just need to make sure qxl_soft_reset
forgets the "ABOUT_TO_SLEEP".
