Before this patch usb_phy_roothub_init served two purposes (from a caller's point of view - like hcd.c): - parsing the PHYs and allocating the list entries - calling phy_init on each list entry While this worked so far it has one disadvantage: if we need to call phy_init for each PHY instance then the existing code cannot be re-used. Solve this by splitting off usb_phy_roothub_alloc which only parses the PHYs and allocates the list entries. usb_phy_roothub_init then gets a struct usb_phy_roothub and only calls phy_init on each PHY instance (along with the corresponding cleanup if that failed somewhere). This is a preparation step for adding proper suspend support for some hardware that requires phy_exit to be called during suspend and phy_init to be called during resume.
