staging: iio: ad2s1210: Remove platform data NULL check in probe

Browse source 
The driver only needs to access GPIOs via GPIOLIB. And SPI can be
configured via device-tree or ACPI.

The platform data is a remnant from another time, and should not cause the
driver to error out during probing if it is NULL.
Also, it's not used.
