Re: [PATCH] chipidea: core: Move hw_phymode_configure() into probe

After this change, USB Host1 port on mx53qsb board is functional.

Talked with IC guys, usbcmd.rst will not reset PORTSC_PTS at chipidea core IP default, unless some vendors changes this behaviour(very low possibilities). So, it is safe to put it at probe, unless we need consider above uncertain change.
