DRM: i915: add mode setting support
This commit adds i915 driver support for the DRM mode setting APIs. Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are supported. HDMI, DisplayPort and additional SDVO output support will follow. Support for the mode setting code is controlled by the new 'modeset' module option. A new config option, CONFIG_DRM_I915_KMS controls the default behavior, and whether a PCI ID list is built into the module for use by user level module utilities. Note that if mode setting is enabled, user level drivers that access display registers directly or that don't use the kernel graphics memory manager will likely corrupt kernel graphics memory, disrupt output configuration (possibly leading to hangs and/or blank displays), and prevent panic/oops messages from appearing. So use caution when enabling this code; be sure your user level code supports the new interfaces. A new SysRq key, 'g', provides emergency support for switching back to the kernel's framebuffer console; which is useful for testing.

+ help
+ Choose this option if you want kernel modesetting enabled by default,
+ and you have a new enough userspace to support this. Running old
+ userspaces with this enabled will cause pain. Note that this causes
+ the driver to bind to PCI devices, which precludes loading things
