drm/i915: Extract i915_module.c The module init code is somewhat misplaced in i915_pci.c, since it needs to pull in init/exit functions from every part of the driver and pollutes the include list a lot. Extract an i915_module.c file which pulls all the bits together, and allows us to massively trim the include list of i915_pci.c. The downside is that have to drop the error path check Jason added to catch when we set up the pci driver too early. I think that risk is acceptable for this pretty nice include.

drm/i915: Sanitycheck PCI BARs For proper operation of i915 we need usable PCI GTTMMADDR BAR 0 (1 for GEN2). In most cases we also need usable PCI GFXMEM BAR 2. Let's add functions to check if BARs are set, and that it have a size greater than 0. In case GTTMMADDR BAR, let's validate at the beginning of i915 initialization. For other BARs, let's validate before first use.
