drm/i915/guc: Remove GUC_CTL_DEVICE_INFO parameter

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
