By switching EPHY_LED4_N_JTRST_N from EPHY_LED4_N to GPIO#39
we can control USB port power an all current revisions of MR3020v3.
It was not a thing on some first revisions, pin was unused.
But for now on all current MR3020v3 boards EPHY_LED4_N_JTRST_N pin
is connected to USB power key.
Also it was not used as EPHY indicator on any revision of the board.
