This driver has been flagged to drop class based instantiation. The removal
improves boot-up time and is unneeded for embedded controllers. Users have been
warned to switch for some time now, so we can actually do the removal. Keep the
DEPRECATED flag, so the core can inform users that the behaviour finally
changed now. After another transition period, this flag can go, too.

Hi Wolfram

Acked-by: Andrew Lunn <andrew@lunn.ch>

As far as i know, none of the arm boards using this driver make use of
class based instantiation. The majority use DT now, the exception
being Orion5x.  So you could jump straight to removing the flag if you
wanted.
