drm: Use a const drm_driver for legacy PCI devices
Now that the legacy PCI support code doesn't need to write to the drm_driver structure, it can be treated as const through the whole DRM core, unconditionally. This allows declaring the structure as const in all drivers, removing one possible attack vector.
