Subject: [PATCH 0/5] Define VDD_MXC for SC8280XP

This has somehow been omitted, leading to potentially stale votes.
On the flip side, the domain will now be powered off, which will
uncover any omissions we've made in the DTs so far.

Reasonably tested on an x13s without pd_ignore_unused (camera still
works).

Video (not upstream right now) will also need this connection.

This series defines VDD_MXC and wires it up to consumers.
