drm/i915/xelpd: Fallback to plane stride limitations when using DPT

GTT remapping allow us to have planes with strides larger than HW
supports but DPT + GTT remapping is still not properly handled so
falling back to plane HW limitations for now.

This patch can be dropped when DPT + GTT remapping is correctly
handled but until then we need this limitation for all display13
platforms to avoid pipe faults.
