Point the OF match table directly to the struct that describes the
device as opposed to an intermediate enum; doing so simplifies the
code and avoids a clang warning.
As part of this change, the I2C device ID table is removed, as the
device cannot probe without an OF node due to the unique nature of
the hardware's interrupt pin.

The vendor has introduced a new variant of silicon which is highly
similar to the existing IQS7222A, but with its independent sliders
essentially replaced with a single-contact trackpad.
Update the common driver to support this new device's register map
and report trackpad events. As with the IQS7222A, the new IQS7222D
can report both raw coordinates as well as gestures.

Extend the common binding to include a new variant of the silicon,
which effectively replaces a pair of slider nodes with a trackpad
node comprising the same or similar properties.
As part of this change, the if/then/else schema have been updated
to identify properties that are not supported by the new device.

If the device drops into ultra-low-power mode before being placed
into normal-power mode as part of ATI being triggered, the device
does not assert any interrupts until the ATI routine is restarted
two seconds later.
Solve this problem by adopting the vendor's recommendation, which
calls for the device to be placed into normal-power mode prior to
being configured and ATI being triggered.
The original implementation followed this sequence, but the order
was inadvertently changed as part of the resolution of a separate
erratum.
