[PATCH v2 4/6] drm/xe/display: Use the correct calculation for phys_base on integrated

[Maarten Lankhorst <dev@lankhorst.se>]

The code originally assumed there was a 1:1 mapping between
stolen and GGTT offset. This is no longer true as of MTL, so
perform the correct calculations, similar to how they're
performed for the DGFX case.
