Roughly based on how nouveau is handling it. Instead of
adding the bo_va when the address is set add the bo_va
when the handle is opened, but set the address to zero
until userspace tells us where to place it.

This fixes another bunch of problems with glamor.

The AMD ACPI interface may use ACPI_VIDEO_NOTIFY_PROBE to signal SBIOS
requests; block the keypress in this case since the user did not
actually press the mode switch key.
Signed-off-by: NLuca Tettamanti <kronos.it@gmail.com>
Signed-off-by: NAlex Deucher <alexander.deucher@amd.com>

The standard video events may be overloaded for device specific
purposes. For example AMD ACPI interface overloads
ACPI_VIDEO_NOTIFY_PROBE (0x81) to signal AMD-specific events. In such
cases we don't want to send the keypress (KEY_SWITCHVIDEOMODE) to the
userspace because the user did not press the mode switch key (the
spurious keypress confuses the DE which usually changes the
display configuration and messes up a dual-screen setup).
This patch gives the handlers the chance to examine the event and
block the keypress if the event is device specific.
