net: tsec: Access TBI PHY through the corresponding MII
When an eTSEC is configured to use TBI, configuration of the TBI is done through the MIIM registers for that eTSEC. For example, if a TBI interface is required on eTSEC2, then the MIIM registers starting at offset 0x2_5520 are used to configure it.
