Correct return value check of gtp_read_fw_version, called in probe
of the Goodix driver. The return value is actually the number of
registers read through gtp_i2c_read() function call.
Also change the error message of gtp_check_product_id.

Add dynamic detection support to goodix driver, where
the driver tries to read the chip id and make sure
it is communicating with the right chip.
gtp_read_version is modified to gtp_read_fw_version
which reads the firmware version from the controller
and will be used during fw update process.

This could make sure that no wake up is pending from FW
and if initial wake up is received then failing suspend_noirq
should trigger resume.

In synaptics_dsx_2.6 touch driver, secure_touch_init tries to get
the QUP clocks for the secure touch functionality. But as these
calls are optional and TZ might get the owenership of these clocks,
this change removes the error return statement, so that the
secure touch can be initialized properly.
