Remove old PPC4xx EMAC driver

Please post a diff, along with a description of the changes.

One huge patch to "remove emac driver" and another huge patch to "add 
emac driver" is quite silly.

This patch replaces current PowerPC 4xx EMAC driver with
new, re-written version.

New driver uses NAPI, it solves stability problems under heavy packet 
load and low memory, corrects chip register access and fixes numerous 
small bugs I don't even remember now :).

This patch has been tested on all supported in 2.6 PPC 4xx boards.
It's been used in production for almost a year now on custom
4xx hardware. PPC32 specific parts are already upstream.

Patch was acked by the current EMAC driver maintainer (Matt Porter). I
will be maintaining this new version.

Patch is quite big (~234K) because there is virtualy 0% of common code 
between old and new version.
