Subject: drm/amd/display: Fix compile error on older GCC versions
Git-commit: 1a2eaed80a0bd19f69da880d87f037f5829fb664
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

GCC 4.9 reports a 'missing braces around initializer' error. This is a
bug, documented here:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119

Fix it by adding another brace.
