input: synaptics: add support for unprogrammed panels

Some unprogrammed touch panels from touch vendor and
wrongly programmed touch panels from factory may
return incorrect touch sensor coordinate range when
their query registers are read via I2C transaction,
but these panels work fine in the field otherwise
and their data registers give correct coordinates.
These panels give incorrect coordinates range because
either they are not programmed with a firmware file
or there was an error in programming the firmware.
In such a scenario, touch driver should not compare
the coordinate ranges retreived from touch sensor
and DT node and allow the driver operation to continue
normally.
