usb: hub: Parallelize power-cycling of root-hub ports Untill now we power-cycle (aka: disable power on a port and re-enabling again) one port at a time. Delay of 20ms for Port-power to change multiplies with number of ports in this case. So better we parallelize this process: disable power on all ports, wait for port-power to stabilize and then re-enable the power subsequently. Signed-off-by: Vivek Gautam <gautam.vivek@samsung.com>
