ARM i.MX ehci: factor out soc specific functions
Currently we have a mxc_initialize_usb_hw which is called on every i.MX SoC. This function dispatches the different SoC types, which is quite ugly. This patch moves the SoC specific USB initialization to their correspondive mach directories. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
