usb: chipidea-imx: Fix usb initialization
This patch fix chipidea-imx usb initialization.
"imx_chipidea_port_init" was moved before PORTSC setup in the
commit "USB i.MX chipidea: implement post init support". This
change breaks usb function with ULPI. Patch moves port initialization
back after PORTSC setup, so it works again.
