[Intel-gfx] [PATCH 0/2] Couple of patches on top of the SKL latency retrieval

[Damien Lespiau]

Ville had 2 comments on the SKL memory latency patch that are better addressed
as separate patches on top.

Patch 1: SKL unifies the plane hw and their latencies to fech data from memory
is identical. So SKL only needs a single array. We save some room by using
anymous union/structs. However, last time I tried that (shared DPLL state),
Daniel didn't like it. So separate that into its own patch so it can be easily
rejected.

Patch 2: While it shouldn't cause any harm and DATA1 is likely unused by the
pcode firmware, we don't actually know. So it's better to have as a separate
patch, just in case a revert is needed (for testing or otherwise).
