r8152: move the settings of PHY to a work queue
Move the settings of PHY to a work queue and schedule it after rtl_ops.init(). There are some reasons for this. First, the settings are only needed for the first time initialization or after the power down occurs. Second, the settings are independent with the others. Last, the settings may take more time than the others. Leave they in probe() or open() may delay the following flows. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.
