The host<->driver channel is the shared-memory section (hidclass blocks the device
stack and UMDF has no control device), so the first-attempt in-driver IOCTL channel
never fired. Remove it: the custom device interface, IOCTL_PFDS_SET_INPUT/GET_OUTPUT,
the output queue, and the on_set_input/complete_one_read/deliver_output helpers. The
driver keeps the HID handshake, the 8ms read timer fed from the shared section, and
on_output_report publishing the game's 0x02 to the section. Rebuilt + reloaded + the
channel still verifies both directions live on the RTX box.
Also list `pf_dualsense` as a second hardware id (alongside `root\pf_dualsense`) so the
host's SwDeviceCreate'd software device binds the same driver as a devgen one.
