According to the AR8035 datasheet:
"When using crystal, the clock is generated internally after power is
stable. For a reliable power on reset, suggest to keep asserting the reset
low long enough (10ms) to ensure the clock is stable and clock-to-reset 1ms
requirement is satisfied."
Pass the 'phy-reset-duration' property to meet such requirement.
