From: Tom O'Rourke <Tom.O'Rourke@intel.com>

This patch adds has_slpc to skylake info.

The SLPC interface has changed and could continue to
change. Only GuC versions known to be compatible are
supported here.

v1: Move slpc_version_check to intel_guc_ucode_init.
fix whitespace (Sagar)
Moved version check to different patch as has_slpc
should not be updated based on it. Instead module parameter
should be updated based on version check. (Sagar)
Added support to skylake_gt3 as well. (Sagar)
