intel: Store pointer to struct intel_device

Beware the barbarians at the gate, who invade and steal your ScrnInfoPtr
and its Entity from underneath you. In some configurations, we lose
access to the struct intel_device stored on the Entity after
initialisation, causing havoc. Workaround this by storing the
intel_device that we open in our driverPrivate.
