mlxsw: core: Add support for module EEPROM read by page
Add support for ethtool_ops::get_module_eeprom_by_page() which allows
user space to read transceiver module EEPROM based on passed parameters.
The I2C address is not validated in order to avoid module-specific code.
In case of wrong address, error will be returned from device's firmware.
Tested by comparing output with legacy method (ioctl) output.
