MIPS: BCM63XX: provide DMA masks for ethernet devices 
The switch to the generic dma ops made dma masks mandatory, breaking
devices having them not set. In case of bcm63xx, it broke ethernet with
the following warning when trying to up the device:

Fix this by adding appropriate DMA masks for the platform devices.
