HID: i2c-hid: reset Synaptics SYNA2393 on resume

[ Upstream commit 538f6740 ]

On the Dell XPS 9570, the Synaptics SYNA2393 touchpad generates spurious
interrupts after resuming from suspend until it receives some input or
is reset. Add it to the quirk I2C_HID_QUIRK_RESET_ON_RESUME so that it
is reset when resuming from suspend.
