drm/i915/guc: Make intel_guc_send a function pointer
Prepare for an alternate GuC communication interface.
v2: Make a few functions static and name them correctly while we are at it (Oscar), but
leave an intel_guc_send_mmio interface for users that require old-style communication.
v3: Send intel_uc_init_early back to the top (Michal).
