Subject: [PATCH net-next] net: phy: realtek: increase rtl822x_c45_soft_reset() poll timeout

It's noticed that sometimes RTL8221B-VB-CG cannot be reset properly.
Increase the polling timeout value to fix this issue. The generic
phy reset function genphy_soft_reset() also uses 600ms as the timeout
threshold.
