ramips: ethernet: ralink: do a reset of the ethernet & switch together

The ethernet and switch needs to have the reset at the same time to
ensure a DMA panic doesn't happen.
The DMA panic seems to only happen on the rt503x devices as the SoCs
can have different versions on the ethernet, switch and DMA cores.

Do a partial revert of the reset api change and ignore the reset controller.
