Subject: [PATCH] Support future Qxl revisions

The driver determines operation mode
(QXL or VGA) by checking device hardware
ids including revision id field.

Without this patch driver operates in VGA
mode for all revisions other than 4.

This patch makes driver operate in QXL
mode revision 4 and newer devices.
