This converts from using a platform device for the CFGCHIP syscon
regmap to using platform data to pass the regmap to consumers.
A lazy getter function is used so that the regmap will only be
created if it is actually used. This function will also be used
in the clock init when we convert to the common clock framework.
The USB PHY driver is currently the only consumer. This driver is
updated to use platform data to get the CFGCHIP regmap instead of
syscon_regmap_lookup_by_pdevname().

It will be nice to have the discussion link as part of commit description.

Kishon,
With your ack I would like to queue this through the DaVinci tree for
v4.17. Due to ongoing common clock framework conversion effort, I expect
to queue a number of other patches dependent on this.
Once v4.16-rc1 comes out, I can provide an immutable commit/tag with
just this patch applied. You can use that if you end up queuing other
patches which conflict with this.
Let me know.
Thanks,
Sekhar
