> E822 PHY TS registers should not be written and the only way to clean up
> them is to reset QUAD memory.
>
> To ensure that the status bit for the timestamp index is cleared, ensure
> that ice_clear_phy_tstamp implementations first read the timestamp out.
> Implementations which can write the register continue to do so.
>
> Add a note to indicate this function should only be called on timestamps
> which have their valid bit set. Update the dynamic debug messages to
> reflect the actual action taken.
