[Intel-gfx] [Intel-gfx 6/6] drm/i915/guc: Move guc_log_relay_chan debugfs path to uc

[Alan Previn <alan.previn.teres.alexis@intel.com>]

All other GuC Relay Logging debugfs handles including recent
additions are under the 'i915/gt/uc/path' so let's also move
'guc_log_relay_chan' to its proper home.
