Add anatop phandle which is used to access anatop registers to
control PHY's power and other USB operations.

no related to this patch, but this feels like OMAP's System Control
Module (a rather simplistic IP which control power for a few other IPs).

We're starting to see a pattern here, eventually we will need a more
generic approach to such types of modules. For now, don't worry :-)

We use syscon (system controller) driver (drivers/mfd/syscon.c)
to handle it, syscon uses regmap to visit register which can keep
register access exclusively.
