[RESEND PATCH v3] tpm: st33zp24: remove pointless checks on probe

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

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.
