PATCH RESEND v3 1/1 tpm: st33zp24: remove pointless checks on probe

Remove tests for SPI device or I2C client to be non-NULL because driver core will never call driver's probe method without having a valid device structure.

---

v3: no changes
v2: reworked commit message

This was a part of a 3-patch series, the first 2 dealt with dropping support for platform data and converting the driver to gpiod API, and were applied, this one got reviewed-by from Jarkko but for some reason was left out.
