tpm: tis_i2c: Add compatible string nuvoton,npct75x

Add "nuvoton,npct75x" as well as the fallback compatible string
"tcg,tpm-tis-i2c" to the TPM TIS I²C driver.  They're used by:

  arch/arm/boot/dts/aspeed/aspeed-bmc-ibm-bonnell.dts
  arch/arm/boot/dts/aspeed/aspeed-bmc-ibm-everest.dts

And by all accounts, NPCT75x is supported by the driver:
