commit 101da426 upstream.

Use the device of the device tree node should be rather than the
device of the struct net_device when allocating DMA buffers.

The driver got away with it on sparc32 until commit 53b7670e
("sparc: factor the dma coherent mapping into helper") after which the
driver oopses.

Fixes: 6cec9b07 ("can: grcan: Add device driver for GRCAN and GRHCAN cores")
