Subject: [PATCH v1 7/8] tpm: tis-i2c: Add more compatible strings

From: Joel Stanley <joel@....id.au>

The NPCT75x TPM is TIS compatible. It has an I2C and SPI interface.

https://www.nuvoton.com/products/cloud-computing/security/trusted-platform-module-tpm/

Add a compatible string for it, and the generic compatible.
