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: [ef82be00] [c01c4da4] get_new_skb+0x28/0xf8 (unreliable) [ef82be20] [c01c4eb8] rx_bd_buffer_set+0x44/0x98 [ef82be40] [c01c62bc] ucc_geth_startup+0x11b0/0x147c [ef82be80] [c01c6674] ucc_geth_open+0xec/0x2a4 [ef82bea0] [c02288a4] dev_open+0xc0/0x11c [...] Fix this by passing of_device's device that specifies DMA ops in its archdata.
