Change device_unregister() to put_device() call before returning from the function. As comment of device_add() says, 'if device_add() succeeds, you should call device_del() when you want to get rid of it. If device_add() has not succeeded, use only put_device() to drop the reference count'. Found by code review.

Convert all platform drivers below drivers/phy/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

This API is used to identify the USB port that is associated with a given PHY. The function takes a PHY pointer for either a USB2 PHY or USB3 PHY as input and returns the corresponding port number. If the PHY pointer is invalid, it returns -ENODEV.
