usb-hub: set PORT_STAT_C_SUSPEND on host-initiated wake-up
PORT_STAT_C_SUSPEND should be set even on host-initiated wake-up,
i.e. on ClearPortFeature(PORT_SUSPEND). Windows is known to not
work properly otherwise.
Side note, since PORT_ENABLE looks similar and might appear to
have the same issue: According to 11.24.2.7.2.2 C_PORT_ENABLE:
"This bit is set when the PORT_ENABLE bit changes from one to
zero as a result of a Port Error condition (see Section 11.8.1).
This bit is not set on any other changes to PORT_ENABLE."
