[PATCH 11/14] ARM: OMAP2+: omap4panda: Provide USB Host's PHY platform data

[Roger Quadros <rogerq@ti.com>]

Provide platform data for the USB host's PHY.

Also get rid of managing PHY clock. This will now be done by the phy driver.
For that to work we create a clock alias that links the PHY clock name to the
PHY device name.
