media: ts2020: fix null-ptr-deref in ts2020_probe()

KASAN reported a null-ptr-deref issue when executing the following command:

The cause of the problem is that when using sysfs to dynamically register an i2c device, there is no platform data, but the probe process of ts2020 needs to use platform data, resulting in a null pointer being accessed.

Solve this problem by adding checks to platform data.
