Subject: drm/i915: Return a default RCS context size
Git-commit: 7ab4adbd921f9ab69bbe10cc1354a9fb59085a71
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Instead of returning whatever size the latest GEN used. This is because
context sizes for new GENs can go up or down, but the only safe thing to
do for missing cases is to use the largest known one, whatever that is.
