sna: Expand packed KMS structs for 64-bit alignment
Pavel Roskin found that with a 32-bit build of the DDX with a 64-bit
kernel that the call to GETCONNECTOR was overwriting the 4 bytes beyond
the end of the drm_mode_get_connector structure. This would appear to be
due to the surreptious padding inserted by the compiler so that the
structure would be naturally aligned on a 64-bit system. To compenstate
we need to insert padding between the adjacent 32-bit structures on the
stack.
As usual, be paranoid and make sure that all the adjacent KMS structs we
use are padded out to an 64-bit boundary.

sna: Disable updating properties upon reading their values
When we assign the hardware values to the output properties, we do not
need to process the set_property callback to write those values back to
hardware. This callback is triggered by the pending update flag passed
to RRChangeOutputProperty.

sna: Preserve the user backlight value for get_property calls
When querying the current backlight value, be sure not to overwrite the
last user set value by the call to RRChangeOutputProperty.
RRChangeOutputProperty calls into set_backlight_property, tricking us
into believing that the user has set a new backlight value. The result
is that we end up believing that the user chooses a 0 backlight if she
should happen to query the property whilst the output is disabled.
