drm/i915: Depend on !PREEMPT_RT.
There are a few sections in the driver which are not compatible with
PREEMPT_RT. They trigger warnings and can lead to deadlocks at runtime.
Disable the i915 driver on a PREEMPT_RT enabled kernel. This way
PREEMPT_RT itself can be enabled without needing to address the i915
issues first. The RT related patches are still in RT queue and will be
handled later.
