Nope, didn't worked. This parameter is a pulse width of a reset, but the 
issue is about having a delay *after* reset. However, introducing a new 
`phy-reset-wait` is a reasonable option. Thanks for idea, I will make a 
patch, and then it's up to you and Anatolij to decide whether it is a ok 
or not.
