ucc_geth: Pass proper device to DMA routines, otherwise oops happens

The driver should pass a device that actually specifies internal DMA
ops, but currently it passes netdev's device, which is wrong and that
causes following oops:

Kernel BUG at c01c4df8 [verbose debug info unavailable]
Oops: Exception in kernel mode, sig: 5 [#1]
[...]
NIP [c01c4df8] get_new_skb+0x7c/0xf8
LR [c01c4da4] get_new_skb+0x28/0xf8
Call Trace:

[ef82bea0] [c02288a4] dev_open+0xc0/0x11c
[...]

Fix this by passing of_device's device that specifies DMA ops in its
archdata.
