For AML devices, there are some issues where the wrong module
indentified then configure PHY failed.

The module info buffers should be initialized to 0 before the firmware
returns information. And DECLARE_PHY_INTERFACE_MASK() does not guarantee
zeroed contents, so explicitly clear the temporary interface masks before
setting supported interfaces.

Rework txgbe_identify_module() to validate module identifiers through
explicit type checks instead of relying on transceiver_type heuristics.
When using the SFP module, transceiver_type could be a random value,
because it was read from an invalid register.
