Subject: drm/i915/guc: Remove GUC_CTL_DEVICE_INFO parameter
MIME-Version: 1.0

Git-commit: 5bbed0b38dd02dfb58d195487ef5b23e74b8b6c1
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
It looks that GuC does not actively use GUC_CTL_DEVICE_INFO parameter
where we are passing GT type and Core family values.
Let's stop/remove setup of this parameter and remove related
definitions.
v2: (this time without squashed HAX)
- New title and description
- Remove also GUC_CORE_FAMILY_* definitions (Michel)
v3:
- The removed define GUC_CTL_DEVICE_INFO has been restored (Michel)
- Updated description (Sagar)
v4: rebase
