usb: phy: qmp: change orientation to default portselect mode

if there are two modules control one same pin,
each module will request and release one state,
there is race when one module request state before
another module complete relase it's state.
revert to commit 87aee0bf ("usb: phy: qmp: Perform
DP_COM_SW_RESET during portselect") to allow only one module
control one pin.
