[Skiboot] [PATCH 3/3] tpm_i2c_nuvoton: add nuvoton, npct601 to the compatible property

[Claudio Carvalho]

The linux kernel doesn't have a driver compatible with
"nuvoton,npct650", but it does have for "nuvoton,npct601", which should
also be compatible with npct650.

This adds "nuvoton,npct601" to the compatible devtree property.
