Add a linked list for keeping multiple PHY instances with different
types so that we can have separate USB2 and USB3 PHYs on one single
board. _get_phy_ has been changed so that the controller gets
the transceiver by type. _remove_phy_ has been added to let the phy
be removed from the phy list.

_transceiver() in otg.c is replaced with _phy. usb_set_transceiver is
replaced with usb_add_phy to make it similar to other usb standard
function names like usb_add_hcd.

Use struct usb_otg members with OTG specific functions instead
of usb_phy members.

This patch converts the drivers in drivers/power/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

The ISP1704/1707 chip can be put to full power down
state by asserting the CHIP_SEL line. This patch enables
platform or board specific hooks to put the device into
power down mode in case not needed.

This patch is a preparation for enabling this powering
routine in n900 (rx-51) devices.

Thanks to Heikki Krogerus for helping out with the patch.

If the device is booted up with cable connected, or the
module is loaded after plugging in the cable, the
notification has come and gone, so not relying on it at
probe time. Instead this checks the VBUS level manually
after probe.

To avoid breaking high speed chirp handshaking with CDP
chargers, no more then 500mA should be drawn. To make sure
of this, utilizing current_max property. After the device
has enumerated, it's safe to draw the maximum 1800mA as
defined in the Battery Charging Specification. This can be
also used with normal USB connection if the controller sends
ENUMERATED notification with the milliamps as data.

From now on the online property indicates VBUS, present
property if there is a charger and current_max the milliamps
possible to draw from VBUS.
