PSA and encrypted image support status

[stindaNXP]

Hi

What's the current status of PSA API support using the encrypted image feature?

In the current 2.2.0 version, there are some build issues when I choose the PSA backend by MCUBOOT_USE_PSA_CRYPTO. I was able to fix them, but the boot flow fails when extracting the private key. I can see there are a lot of FIXMEs and TODOs in encrypted_psa.c, PSA is enabled only for RSA and not EC.... Some are fixed in the main branch in recent commits, so I am wondering if it will be fixed in the next release?
