Peter Chen cd84f009e9 usb: chipidea: coordinate usb phy initialization for different phy type 
For internal PHY (like UTMI), the phy clock may from internal pll,
it is on/off on the fly, the access PORTSC.PTS will hang without
phy clock. So, the usb_phy_init which will open phy clock needs to
be called before hw_phymode_configure.
See: http://marc.info/?l=linux-arm-kernel&m=139350618732108&w=2

For external PHY (like ulpi), it needs to configure portsc.pts before
visit viewport, or the viewport can't be visited. so phy_phymode_configure
needs to be called before usb_phy_init.
See: cd0b42c2a6

It may not the best solution, but it can work for all situations.
