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 ?
