DM: Add UOS boot option of "i915.enable_guc_loading=0" to fix incorrect memory allocation on APL-NUC

Browse Source 
The Global GTT on i915 GPU is allocated from SOS based on the partition rule.
As there is no parameter of "enable_guc_loading" for UOS, it causes that the
allocated range of Global GTT is beyond the supported range on UOS. Then the
i915 driver fails to be loaded.

V1->V2: Fix one typo error. It should be "i915.enable_guc_loading=0"
instead of "i915.enable_guc_loading=1".
