Subject: [PATCH net-next 9/9 v4] net: ethernet: ixp4xx: Use parent dev for DMA pool

Use the netdevice struct device .parent field when calling
dma_pool_create(): the .dma_coherent_mask and .dma_mask
pertains to the bus device on the hardware (platform)
bus in this case, not the struct device inside the network
device. This makes the pool allocation work.

ChangeLog v3->v4:
- Drop a stable tag and rebubmit.
ChangeLog v2->v3:
- Rebased on v5.5-rc1
ChangeLog v1->v2:
- Rebase with the rest of the series.
- Tag for stable, this is pretty serious.
- I have no real idea when this stopped working.
