Subject: [PATCH] drm/i915/gvt: add PLANE_KEYMAX regs to mmio track list
Git-commit: 03fa9350c30b5db827e9b155715df09660ba28b1
Patch-mainline: v4.16-rc1
References: FATE#322643 bsc#1055900

Running 4.15 Linux kernel in VM will cause host GVT reports
'untrack mmio 0x701a0' errror, which identifies the PLANE_KEYMAX
registers. Add them to track list.

V2: rebase to latest staging code.
