This patch removes the superflous .owner field for drivers which
use the module_platform_driver or platform_driver_register api,
as this is overriden in __platform_driver_register.

In case of multi-phy PHY providers, each PHY should be modeled as a sub
node of the PHY provider. Then each PHY will have a different node pointer
(node pointer of sub node) than that of PHY provider. Added this provision
in the PHY core.
Also fixed all drivers to use the updated API.

The USB phy controller in the A31 differs mostly from the older controllers
because it has a clock dedicated for each phy, while the older ones were having
a single clock for all the phys.

Move the phy initialization and variables declaration to the loop itself, since
it is where it really belongs. Also remove all the temporary variables, we can
use the structure members directly.

The Allwinner A1x / A2x SoCs have 2 or 3 usb phys which are all accessed
through a single set of registers. Besides this there are also some other
phy related bits which need poking, which are per phy, but shared between the
ohci and ehci controllers, so these are also controlled from this new phy
driver.
