HID: mcp2221: don't connect hidraw

commit 67c90d14018775556d5420382ace86521421f9ff upstream.

The MCP2221 driver should not connect to the hidraw userspace interface,
as it needs exclusive access to the chip.

If you want to use /dev/hidrawX with the MCP2221, you need to avoid
binding this driver to the device and use the hid generic driver instead
(e.g. using udev rules).
