From: Tom O'Rourke <Tom.O'Rourke at 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.

On Skylake, GuC firmware v6 is supported.  Other
platforms and versions can be added here later.

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)
