From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx>
We had these intel_aux_display_runtime_{get,put} abstractions that
would just get/put PC8 references, but now that runtime PM and PC8
are the same stuff, we just need the runtime PM references, so just
get/put runtime PM directly, because that's what the rest of our code
does.
Another way to solve this problem would be to add DP_AUX and GMBUS
power domains, and then use intel_display_power_{get,put}, but every
power domain already gets/puts runtime PM references, so this would
just make things more complex.
