Fix up the root-hub descriptor to accommodate the variable-length DeviceRemovable and PortPwrCtrlMask fields, while marking all ports as removable (and leaving the reserved bit zero unset). Also add a build-time constraint on VHCI_HC_PORTS which must never be greater than USB_MAXCHILDREN (but this was only enforced through a KConfig constant). This specifically fixes the descriptor layout whenever VHCI_HC_PORTS is greater than seven (default is 8).
