Subject: [PATCH] drm/i915/uc: Add message with firmware url
Git-commit: 1e913d27cef4760e247951253bf207333d418268
Patch-mainline: v4.15-rc1
References: FATE#322643 bsc#1055900

In case of firmware fetch failure we should help user
find latest firmware. URL macro duplication from csr.c
will be fixed in upcoming patch.
