[PATCH i-g-t v7 0/4] Verify PTA entries contains expected values

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

According to spec verify PAT entries in reset / suspend scenarios.
Extending parsing to media gt was necessary as it may contain
different PTA values for main / media gts. With this series
I also observe different PAT ATS values on BMGs.

v2: use pat debugfs instead of pat_sw_config
v3: add hw/sw PAT compare subtest
v4: simplify PTA comparison subtest (Matt)
v5: unify PTA/PAT tests
v6: skip on !pf and assert in case of PAT access failure (Wang)
