[TF-M] How to solve the link error while enable both mbedTLS and TF-M crypto interfaces in NSPE

Hi experts,

Recently we're developing an example demo based on TF-M, the application scenario is simplified as below.

MbedTLS module in NSPE is used to guarantee the secure communication with AWS cloud, while TF-M in SPE provides data encryption/decryption and sensitive data storage services.

So both TF-M interfaces and mbedtls module are enabled on NSPE, there will be two implementations of PSA Crypto and this will result in a link error. The red box displays files with conflicts between mbedtls and TF-M, which prevent the project from compiling. Can all TF-M code be converted into a lib to avoid linking issues? Or is there any other way to solve this problem?
