drm/xe/xe2: Program PAT tables

The PAT tables become significantly more complicated on Xe2 platforms.
They now control L3, L4, and coherency settings, as well as additional
characteristics such as compression.

Aside from the main PAT table, there's an additional register that
also needs to be programmed with PAT settings for PCI Address
Translation Services.
