Creating a software node and supplying that for the device
instead of only the device properties in it. A software
node was always created in any case to hold the additional
device properties, so this change does not have any real
effect.
This change makes it possible to remove support for the
problematic "dangling" device properties from i2c subsystem,
i.e. the "properties" member from struct i2c_board_info. The
problems caused by them are not related to this driver.

Newer controllers, such as Voxel, Delbin, Magple, Bobba and others, do not
need to be reset after issuing power-on command, and skipping reset saves
at least 100ms from resume time.
Note that if first attempt of re-initializing device fails we will not be
skipping reset on the subsequent ones.

There are some version of Elan trackpads that send incorrect data when
in SMbus mode, unless they are switched to use 0x5f reports instead of
standard 0x5e. This patch implements querying device to retrieve chips
identifying data, and switching it, when needed to the alternative
report.

Newer controllers (identified as "pattern" version 2) send higher
resolution reports, with 16-bit X and Y coordinates (previous generations
used 12-bit values). These new high resolution reports use report ID of
0x60.
SMbus controllers use the same buffer size for both the new and old
reports, and because of that high resolution reports no longer carry
area of contact data with SMbus.

On older controllers IC type is reported in the 2nd byte of
ETP_I2C_OSM_VERSION_CMD, however if controller's firmware is not flashed
correctly it may return incorrect data. Fortunately there is also
ETP_I2C_IAP_VERSION_P0_CMD command that can be used when controller in
either normal or IAP mode, and which is guaranteed to return accurate data,
so let's use it.
