DW ethernet controller on HSDK hangs sometimes after SW reset, so
add reset node to make possible to reset DW ethernet controller HW.

Changes v2 -> v3:
* Remove v1 suffix as we finaly got rid of v1 suffix in reset
driver and docs.
* Rename reset node to "reset-controller" for consistency with
the other bindings.

Changes v1 -> v2:
* Enable HSDK reset driver in hsdk_defconfig

Revisiting this given that changes to driver have been merged upstream: we currently carry a reset workaround for axs+ethernet, i.e. your patch

ARC: [plat-axs103] Add temporary quirk to reset ethernet IP

But there's nothing similar for HSDK. IOW, we don't need to revert anything foro hsdk, after this gets applied ?
