Lucas De Marchi df04b152fc drm/xe/display: Fix ADL-N detection
Contrary to i915, in xe ADL-N is kept as a different platform, not a
subplatform of ADL-P. Since the display side doesn't need to
differentiate between P and N, i.e. IS_ALDERLAKE_P_N() is never called,
just fixup the compat header to check for both P and N.

Moving ADL-N to be a subplatform would be more complex as the firmware
loading in xe only handles platforms, not subplatforms, as going forward
the direction is to check on IP version rather than
platforms/subplatforms.

Fix warning when initializing display:

	xe 0000:00:02.0: [drm:intel_pch_type [xe]] Found Alder Lake PCH
	------------[ cut here ]------------
	xe 0000:00:02.0: drm_WARN_ON(!((dev_priv)->info.platform == XE_ALDERLAKE_S) && !((dev_priv)->info.platform == XE_ALDERLAKE_P))

And wrong paths being taken on the display side.
