enetc: update TSN Qbv PSPEED set according to adjust link speed
ENETC has a register PSPEED to indicate the link speed of hardware. It is need to update accordingly. PSPEED field needs to be updated with the port speed for QBV scheduling purposes. Or else there is chance for gate slot not free by frame taking the MAC if PSPEED and phy speed not match. So update PSPEED when link adjust. This is implement by the adjust_link.
