HID: i2c-hid: Add no-irq-after-reset quirk for 0911:5288 device
Several cheap Apollo Lake based laptops / 2-in-1s use an i2c-hid mt touchpad which is advertised by the DSDT with an ACPI HID of "SYNA3602", this touchpad can be found on e.g. the Cube Thinker and the EZBook 3 Pro. On my "T-bao Tbook air" the i2c-hid driver fails to bind to this touchpad: "i2c_hid i2c-SYNA3602:00: failed to reset device.". After some debuging this it seems that this touchpad simply never sends an interrupt after a reset as expected by the i2c hid driver. This commit adds a quirk for this device, making i2c_hid_command sleep 100ms after a reset instead of waiting for an irq, fixing i2c-hid failing to bind to this touchpad.
