MBEDTLS_PSA vs TINYCRYPT 5% more flash usage

[Shahin97]

Hello, 

I have recently upgraded from v2.9 to v3.0.1 and have noticed that the mesh security has changed from CONFIG_BT_MESH_USES_TINYCRYPT to CONFIG_BT_MESH_USES_MBEDTLS_PSA,

see https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/bt/bt_mesh/configuring.html#security_toolbox

MBEDTLS_PSA uses 5% more flash over TINYCRIPT, 

Is there any ram reduction Kconfigs I can look into as my application no longer fits in my image size.

Thank you, 

Shahin
