drm/xe: Use pat_index to encode pde/pte

Change the xelp_pte_encode() and xelp_pde_encode() functions to use the
platform-dependent pat_index.  The same function can be used for all
platforms as they only need to encode the pat_index bits in the same
pte/pde layout. For platforms that don't have the most significant bit,
as long as they don't return a bogus index they should be fine.

v2: Use the same logic to encode pde as it's compatible with previous
    logic, it's more future proof and also fixes the cache setting for
    PVC (Matt Roper)
