mv643xx_eth: get rid of static variables, allow multiple instances

Move mv643xx_eth's static state (ethernet register block base address
and MII management interface spinlock) into a struct hanging off the
shared platform device.  This is necessary to support chips that
contain multiple mv643xx_eth silicon blocks.
