You are totally right. I'll update the patch and include it together
with all the other GuC patches (less probability of it getting lost in
the depths of the mailing list that way).
Thanks!

Prepare for an alternate GuC communication interface.
v2: Make a few functions static and name them correctly while we are at it
(Oscar)
v3: Leave an intel_guc_send_mmio interface for users that require old-style
communication

As intel_guc_send_mmio() is again public, there is no need to move
intel_uc_init_early() down to this place, it can stay at the top
of the file.
