[V6 PATCH 03/16] usb: ehci: ehci-mv: use PHY driver for ehci

[Chao Xie]

Originaly, ehci driver will call the callbacks in platform data
for PHY initialization and shut down.
With PHY driver, it will call the APIs provided by PHY driver
for PHY initialization and shut down. It removes the callbacks
in platform data, and at same time it removes one block in the
way of enabling device tree for ehci driver.
