The incomplete report flooded after S3 and touchscreen becomes
malfunctioned.
[ 1367.646244] i2c_hid i2c-CUST0000:00: i2c_hid_get_input: incomplete report (58/18785)
[ 1367.649471] i2c_hid i2c-CUST0000:00: i2c_hid_get_input: incomplete report (58/28743)

[ 1367.654287] i2c_hid i2c-CUST0000:00: i2c_hid_get_input: incomplete report (58/56059)

Adding device ID, 04F3:30CC, to the quirk to re-send report description
after resume.

Just a quick note Jiri. Hans pointed me this morning to
https://bugzilla.redhat.com/show_bug.cgi?id=1622695

And I think we should apply the quirk unconditionally as it should be
safe to retrieve the HID descriptor at all times. I am planning on
working on that tomorrow or Thursday when I have access to the XPS
with i2c_hid devices attached to it.

Cheers,
Benjamin
