Input: Switch i2c drivers back to use .probe()

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

Input: cyttsp - use EXPORT_GPL_SIMPLE_DEV_PM_OPS()

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection
against unused function warnings. The new combination of pm_sleep_ptr()
and EXPORT_GPL_SIMPLE_DEV_PMU_OPS() allows the compiler to see the
functions, thus suppressing the warning, but still allowing the unused
code to be removed. Thus also drop the __maybe_unused markings.
It also rolls in the EXPORT_SYMBOL() so that we only export it
if CONFIG_PM_SLEEP.

Input: cyttsp_i2c - Convert to i2c's .probe_new()

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

Input: cyttsp - remove public header

There is nothing in include/linux/input/cyttsp.h that might be of interes
to the kernel at large, so let's move this information into the driver
code and remove the header.

Input: cyttsp - probe from compatibles

The driver (both SPI and I2C interface) should probe from the compatible
strings, cypress,cy8ctma340 etc when using device tree, not as now, where
it is probing implicitly from the I2C/SPI node name "cypress,cyttsp-i2c"
etc.

The drivers have a I2C device ID table that is used to create the module

so these module aliases are never used.

Input: cyttsp - I2C driver split into two modules

Existing I2C code is for TrueTouch Gen3 devices

TrueTouch Gen4 device is using same protocol, will split driver into
two pieces to use common code with both drivers.

Read/Write functions parameter list modified, since shared code will
be used by two separate drivers and these drivers are not sharing same
structs, parameters updated to use common structures.

Input: add Cypress TTSP capacitive multi-touch screen support

Cypress TrueTouch(tm) Standard Product controllers are found in
a wide range of embedded devices. This driver add support for a
variety of TTSP controllers.

Since the hardware is capable of tracking identifiable contacts, multi-touch
protocol type B (stateful) is used to report contact information.

The driver is composed of a core driver that process the data sent by
the contacts and a set of bus specific interface modules. This patch
adds the base core TTSP driver.
