It appears that each DMA channel has its own interrupt and both rings
can be configured (the same way) to handle interrupts.
1. Make ring interrupts code generic (make it operate on given ring)
2. Move napi to ring (so each has its own)
3. Make IRQ handler generic (match ring against received IRQ number)
4. Add (optional) support for TX interrupt

BCM4908 devices have MAC address accessible using NVMEM so it's needed
to use OF helper for reading it.

Hardware comes up with default max frame size set to 1518. When using it
with switch it results in actual Ethernet MTU 1492:
1518 - 14 (Ethernet header) - 4 (Broadcom's tag) - 4 (802.1q) - 4 (FCS)
Above means hardware in its default state can't handle standard Ethernet
traffic (MTU 1500).
Define maximum possible Ethernet overhead and always set MAC max frame
length accordingly. This change fixes handling Ethernet frames of length
1506 - 1514.

1. Fix "ensable" typo noticed by Andrew
2. Fix chipset name in the struct net_device_ops variable

It seems preferred to let compiler optimize code if applicable.
While at it drop unused enet_umac_maskset().
