Currently all module parameters are handled by i915_param.c/h. This
is a problem for display parameters when Xe driver is used.

This patch set adds a mechanism to add parameters specific to the
display. This is mainly copied from existing i915 parameters
implementation with some naming changes and taking into account
varying driver name.

Also all display specific module parameters are moved under display and the
module parameter are all converted as non-writable. This should be ok
as we have writable device parameters under debugfs.

v2:
  - Drop fastboot parameter
  - Include display parameters into i915_capabilities debugfs interface
