HID: quirks: Add ALWAYS_POLL quirk for SIGMACHIP USB mouse

Browse Source 
The SIGMACHIP USB mouse with VID/PID 1c4f:0034 can disconnect and
re-enumerate repeatedly after it has been enumerated if its interrupt
endpoint is not continuously polled.

This was observed with the device reporting itself as "SIGMACHIP Usb
Mouse". Keeping the input event device open avoids the disconnects.

Add HID_QUIRK_ALWAYS_POLL for this device so the HID core keeps polling
it even when there is no userspace input consumer.
