[Intel-gfx] [RFC 02/22] drm/i915/slpc: Add has_slpc capability flag

[tom.orourke at intel.com]

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

Add has_slpc capablity flag to indicate GuC firmware
supports single loop power control (SLPC).  SLPC is
a replacement for some host-based power management
features.
