PATCH 3/3 86xx: mpc8610_hpcd: use ULI526X driver for on-board ethernet

As of current mainline tree, TULIP driver is unusable on MPC8610HPCD boards. There is a patch[1] floating around (and also included in the BSP), which tries to heal the situation, though the ethernet is still unusable. Practically it takes ages to mount NFS filesystem:

VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 180k init
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 OK
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 OK
nfs: server 10.0.0.2 not responding, still trying

So, instead of trying to add uli526x functionality into TULIP driver (which is already bloated enough), I fixed existing ULI526X driver and now it works perfectly well here.

I'm assuming patches that fix the uli526x driver have been accepted by jeff.

After applying this patch and Anton's two ULI driver patches, the ULI drivers works great on an 8610HPCD.
