drm/i915/dpt: Only do the POT stride remap when using DPT

Browse Source 
[ Upstream commit ef5cb493a9acd7d97870d6e542020980ae3f3483 ]

If we want to test with DPT disabled on ADL the POT stride remap
stuff needs to be disabled. Make it depend on actual DPT usage
instead of just assuming it based on the modifier.
