dma_zalloc_coherent() now crashes if no dev pointer is given.
Add a dev pointer to the ltq_dma_channel structure and fill it in the
driver using it.
This fixes a bug introduced in kernel 4.19.

Hi Florian,
Thanks for the review.

changed because the
clocks are now used by a different driver. This should be cleaned up and
a real common clock driver should provide the clocks instead.

This adds the binding for the GSWIP (Gigabit switch) core found in the
xrx200 / VR9 Lantiq / Intel SoC.
This part takes care of the switch, MDIO bus, and loading the FW into
the embedded GPHYs.

This was tested with GSWIP 2.1 found in the VRX200 SoCs, other GSWIP
versions use slightly different PMAC special tags.

When a DMA channel is opened the IRQ should not get activated
automatically, this allows it to pull data out manually without the help
of interrupts. This is needed for a workaround in the vrx200 Ethernet
driver.

The embedded PHYs are only connected to the switch in this SoC
