net: dwmac_meson8b: do not set TX delay in TXID & RXID
When the PHY interface is set as TXID & RXID, the delays should be taken from DT, but first they should not be hardcoded since the PHY driver will set them. Fixes: 798424e857 ("net: designware: add Amlogic Meson8b & later glue driver") Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Ramon Fried <rfried.dev@gmail.com>
