[PATCH v2 0/1] Add more compatibility strings to tpm-tis-i2c

[Ninad Palsule]

The new IBM system1 bmc machine uses Nuvoton TPM chip. I had this commit
as part of the device tree for new machine but reviewer suggested send
the driver commit as separate patch. The version 2 includes common
compatibility string for TPM 2.0.

The patchset for IBM system1 bmc machine device tree is as follows:
