USB: gadget: dummy_hcd: fix hub-descriptor removable fields

Browse source

commit d81182ce30 upstream.

Flag the first and only port as removable while also leaving the
remaining bits (including the reserved bit zero) unset in accordance
with the specifications:

	"Within a byte, if no port exists for a given location, the bit
	field representing the port characteristics shall be 0."

Also add a comment marking the legacy PortPwrCtrlMask field.
