The mxc-ehci driver calls SoC specific phy initialization right after calling board specific initialization. To offer greater flexibility for boards to setup the phy and to get rid of some unnecessary flags in platform data this patch lets the boards call the SoC specific phy initialization and remove it from the driver.
