This fixes a minor bug which went unnoticed during the initial
driver upstreaming review: TCG_CR50 does not exist in mainline
kernels, so remove it.

This is a driver for the Google cr50 I2C TPM interface which is a
custom microcontroller and requires a custom i2c protocol interface
--
2.32.0
Way back when this driver was written the I2C framework
used to insist an ID table be defined even if the driver
did not use it in favor of ACPI/OF matching, so it was
added just to placate the hard I2C framework requirement.
This is no longer the case so we can drop the table and
also convert the driver to the new probe interface.

These are missing changelog. I guess tags are added, and nothing else?

Hi. That is correct, I've only added the tags you suggested on the
first patch, the second patch is identical.
