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

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
