[PATCH v9 04/15] usb: hub: Use assign_bit() in usb_hub_set_port_power()

[Chen-Yu Tsai <wenst@chromium.org>]

usb_hub_set_port_power() open-codes assign_bit(). Just use the
assign_bit() macro instead. This makes subsequent additions to
usb_hub_set_port_power() easier to read.

This change does not introduce any functional changes.

Attributing suggestion to Andy, since the change was originally
requested as part of a review.

Changes since v4:
- New patch (split out from "usb: hub: Power on connected M.2 E-key
  connectors with power sequencing API") (Andy)
