mlxsw: spectrum_ethtool: Add an external speed to PTYS register
Currently, only external bits are added to the PTYS register, whereas there is one external bit that is wrongly marked as internal, and so was recently removed from the register. Add that bit to the PTYS register again, as this bit is no longer internal. Its removal resulted in '100000baseLR4_ER4/Full' link mode no longer being supported, causing a regression on some setups.
