r8152: adjust the settings of ups flags
The UPS feature only works for runtime suspend, so UPS flags only need to be set before enabling runtime suspend. Therefore, I create a struct to record relative information, and use it before runtime suspend. All chips could record such information, even though not all of them support the feature of UPS. Then, some functions could be combined. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
