mlxsw: core: Add support for OSFP transceiver modules 



The driver can already dump the EEPROM contents of QSFP-DD transceiver
modules via its ethtool_ops::get_module_info() and
ethtool_ops::get_module_eeprom() callbacks.

Add support for OSFP transceiver modules by adding their SFF-8024
Identifier Value (0x19).

This is required for future NVIDIA Spectrum-4 based systems that will be
equipped with OSFP transceivers.
