usb: qmp: phy: Make sure QMP PHY reset write is completed
Add explicit memory barrier after programming USB3_PHY_SW_RESET
register which makes sure that above write is not cached. If
this register write is cached, then phy driver is timing out
with checking PCS status. In some cases, L2 cache memory error
is seen when that register write is flushed whereas usb phy
clock is turned off.
