====================
mlxsw: Add support for module EEPROM read by page

Add support for ethtool_ops::get_module_eeprom_by_page() operation.

Patch #1 adds necessary field in device register.

Patch #2 documents possible MCIA status values so that more meaningful
error messages could be returned to user space via extack.

Patch #3 adds the actual implementation.
