mvebu: add reset delays of PHYs for Fortinet FortiGate 50E

Add reset-(de)assert-us to ethernet PHYs on Fortinet FortiGate 50E to
solve instability after HW resetting of PHYs. (ex.: restarting "network"
service, etc...)

Fixes: #13391
Fixes: 102dc5a62506 ("mvebu: add support for Fortinet FortiGate 50E")
