Add a debugfs subdirectory i915_params with all the i915 module parameters. This is a first step, with lots of boilerplate, and not much benefit yet. This will result in a new device specific debugfs directory at /sys/kernel/debug/dri/<N>/i915_params duplicating the module specific sysfs directory at /sys/module/i915/parameters/. Going forward, all users of the parameters should use the debugfs, with the module parameters being phased out. Add debugfs permissions to I915_PARAMS_FOR_EACH(). This duplicates the mode with module parameter sysfs, but the goal is to make the module parameters read-only initial values for device specific parameters. 0 mode will bypass debugfs creation. Use it for verbose_state_checks which will need special attention in follow-up work.
