drm/i915: parameterize SDE hotplug registers
Browse files Browse the repository at this point in the history 
Ice Lake, Tiger Lake and Elkhart Lake all have different port
configurations and all of them can be parameterized the same way to form
the SDE hotplug bitmask. Avoid making them a special case an just use
the parameterized macros.
