HID: sensor-hub: Allow multi-function sensor devices

The Lenovo Yoga C630 has a combined keyboard and accelerometer that
interfaces via i2c-hid. Currently this laptop either has a working
keyboard (if CONFIG_HID_SENSOR_HUB is disabled) or a working accelerometer.
only works on kernels. Put another way, most distro kernels enable
CONFIG_HID_SENSOR_HUB and therefore cannot work on this device since the
keyboard doesn't work!

Fix this by providing a richer connect mask during the probe. With this
change both keyboard and screen orientation sensors work correctly.
