[PATCH v3 2/4] drm/xe/guc: Introduce GUC_FIRMWARE_VER_AT_LEAST helper

[Michal Wajdeczko <michal.wajdeczko@intel.com>]

There are already few places in the code where we need to check GuC
firmware version. Wrap existing raw conditions into a named helper
macro to make it clear and avoid explicit call of the MAKE_GUC_VER.
