intel: Add an Option for disabling native rotation
Just in case we want to debug the native vs software paths and allow
switching without recompiling. For the unfortunate
Section "Device"
Identifier "igfx"
Driver "intel"
Option "HWRotation" "off"
EndSection
default is for us to use HW rotation where available (for speed, reduced
resource usage and reduce power usage).
