Add support for the kernel's 'nomodeset' parameter to PCI-based
fbdev drivers. The option prevents DRM drivers from loading if they
could possibly displace a hardware-agnostic driver that runs on the
firmware framebuffer. It is a fallback for systems on which the
hardware's native driver does not work correctly.
After the work on the aperture helpers and their integration with
fbdev, it can happen that an fbdev driver replaces a hardware-
agnostic DRM driver. Supporting the nomodeset parameter unifies
the behavior among the graphics drivers and subsystems. An fbdev
driver will not replace any hardware-agnostic driver with nomodeset
given.
