mv643xx_eth: Place explicit port number in mv643xx_eth_platform_data
We were using the platform_device.id field to identify which ethernet
port is used for mv643xx_eth device. This is not generally correct.
It will be incorrect, for example, if a hardware platform uses a single
port but not the first port. Here, we add an explicit port_number field
to struct mv643xx_eth_platform_data.
This makes the mv643xx_eth_platform_data structure required, but that
isn't an issue since all users currently provide it already.
