The broken reverse-mode, selected by snps,ps-speed, is configured when the platform provides a valid port speed and a PCS is being used. Both these remain constant after the driver has probed, so the software state doesn't need to be re-initialised each time stmmac_hw_setup() is called (which is called at open and resume time.) Move the software setup of reverse-mode to stmmac_check_pcs_mode() which is called from the driver probe function.
