net: ethernet: oa_tc6: implement internal PHY initialization

Browse source

Internal PHY is initialized as per the PHY register capability supported
by the MAC-PHY. Direct PHY Register Access Capability indicates if PHY
registers are directly accessible within the SPI register memory space.
Indirect PHY Register Access Capability indicates if PHY registers are
indirectly accessible through the MDIO/MDC registers MDIOACCn defined in
OPEN Alliance specification. Currently the direct register access is only
supported.
