facebook/fby35: remove explicit TPM kconfig

There is already a MACHINE_FEATURE ('tpm2') which is enabled on fby35
and pulls in all the necessary kernel config for the TPM2 hardware.
See the fby35 machine config.

```
meta-fby35/conf/machine/fby35.conf:require conf/machine/include/facebook-tpm2.inc
```
