rockchip64-dev: tweak tx/rx delay in network stability patch

Browse source 
seems like this patch headed upstream for rk3328-roc-cc:
https://patchwork.kernel.org/patch/10804863/
doesn't include the tx/rx delay changes in the original rock64 patch:
https://patchwork.kernel.org/patch/10178969/

My testing showed these changes help with a link down and reset that happens on heavy
exchanges, like streaming. Maybe we should sumbit upstream a patch that hadles this as well?
