- New ALPS touchpad (T4, found currently on HP EliteBook 1000, Zbook Stduio
  and HP Elite book x360) support from Masaki Ota

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.

The GamepadBlock game controller adapter needs HID_QUIRK_MULTI_INPUT
to split it up into two input devices. Without this quirk the
adapter is falsely recognized as only one device and mixes up the
inputs of the two connected controllers.

In addition to DEFT, Elecom introduced a larger trackball called HUGE, in
both wired (M-HT1URBK) and wireless (M-HT1DRBK) versions. It has the same
buttons and behavior as the DEFT. This patch adds the two relevant USB IDs
to enable operation of the three Fn buttons on the top of the device.

This reverts commit fcaa4a07d2a4b541e91da7a55d8b3331f96d1865.

As noted by Masaki [1], 0x120A + trackpoint will not be used in mass
production machines, so remove the ID accordingly.
