Move from multitouch protocol A to protocol B, and since some
applications are not working under BTN_2 reporting, all the instances
of HAT are removed along with BTN_2 reporting.

Synaptics firmware maintains internal cache to store a scan of
finger data so that the host reads finger data from this cache.
The firmware updates the cache when the host reads it nonsequentially.
The current driver reads only present finger data, which can cause
unexpected nonsequential access to cache and the cache can be updated
before the host reads the data, resulting in losing finger data coherency.
Modified the driver to access data sequentially even if there are
not present fingers in the middle so that the finger data coherency
can be preserved.

When the touch driver detected an interrupt, it checks the interrupt
status register. If the value of the register is not normal,
such as zero, the touch driver considered it as a problem on the
device and reinitialized the touch device to recover.
This should not happen with normal touch firmware but, the touch
driver also need to ignore this kind of abnormal interrupt
rather than resetting the device, which causing unexpected freezing
during touch operation.

There was a bug on setting the report mode, breaking other bit fields.
Due to this, the firmware jitter filter was disabled, causing
some noises. Expect more stable position report with this correction.

The tool type checking for pen was incorrect.
Sometimes finger touch produces the same condition as PEN which is
width major and minor are all zero.
This wrong detection change the tracking ID, resulting in two finger
touch report even when single touch is used.
Fix the tool type to finger since mako will support only finger.
