net: txgbe: optimize the flow to setup PHY for AML devices

To adapt to new firmware for AML devices, the driver should send the
"SET_LINK_CMD" to the firmware only once when switching PHY interface
mode, and no longer needs to re-trigger PHY configuration based on the
RX signal interrupt (TXGBE_GPIOBIT_3).

In previous firmware versions, the PHY was configured only after receiving
"SET_LINK_CMD", and might remain incomplete if the RX signal was lost.
To handle this case, the driver used TXGBE_GPIOBIT_3 interrupt to resend
the command. This workaround is no longer necessary with the new firmware.

And the unknown link speed is permitted in the mailbox buffer.
