[Intel-gfx] [PATCH 32/44] drm/i915: Move module init/exit to i915_pci.c

2016-06-15 Thread Chris Wilson
The module init/exit routines are a wrapper around the PCI device
init/exit, so move them across.

Note that in order to avoid exporting the driver struct, instead of
manipulating driver.features inside i915_init we instead opt to simply
exit if i915.modeset is disabled.
