If a platform driver wants to add a sysfs group, it has to do so in a
racy way, adding it after the driver is bound.  To resolve this issue,
have the platform driver core do this for the driver, making the
individual drivers logic smaller and simpler, and solving the race at
the same time.

All of these patches depend on the first patch.  I'll take the first one
through my driver-core tree, and any subsystem maintainer can either ack
their individul patch and I will be glad to also merge it, or they can
wait until after 5.3-rc1 when the core patch hits Linus's tree and then
take it, it's up to them.

Thank to Richard Gong for the idea and the testing of the platform
driver patch.
