Simplify driver by splitting common driver data and net dev
private data. In case of dual_emac mode 2 networks devices
are created, each of them contains its own private data.
But 2 net devices share a bunch of h/w resources, that shouldn't
be duplicated.
This patch leads to the following:
- no functional changes
- reduce code size
- reduce memory usage
- reduce number of conversion to priv function
- reduce number of arguments for some functions
- increase code readability
- create prerequisites to add multichannel support,
  when channels are shared between net devices

Even if it sounds reasonable, I have to NACK this patch -
main reason below, but there are few more:
- could you pls split this change as it's too big and I'm pretty sure it's possible;
- could you pls avoid unrelated changes like variable reordering in structures

and thanks a lot for working on this.

Sry, but NACK - no new static variables pls.
