Include PDx86 mailing list to the list of that. Current SURFACE*
drivers have per driver record in MAINTAINERS IIRC. So, update them as
well if needed.

Don't repeat parts of the path, the aggregator is enough as a folder
name, but the driver of course should be in its own namespace

(Not sure why it's not a part of aggregator folder)

Respective subsystem _if_ it is a subsystem related driver and not
kinda board file. Use common sense and existing examples.
