Update events from:
v1.31 -> v1.33 for alderlake
v1.09 -> v1.12 for arrowlake
v1.14 -> v1.16 for emeraldrapids
v1.10 -> v1.12 for graniterpaids
v1.14 -> v1.17 for lunarlake
v1.14 -> v1.16 for meteorlake
v1.28 -> v1.30 for sapphirerapids
Update TMA 5.0 to 5.1 removing the slots event workaround as the patch series:
https://lore.kernel.org/lkml/20250719030517.1990983-1-irogers@google.com/
