Revert "Enable entropy injection on PSA targets"

mbedtls performs selftest on all entropy sources.
Enable injected source without proper entropy injection causes mbedtls
selftest to fail.

Application code can still enable entropy injection by adding the macros
to mbed_app.json/mbed_lib.json

This reverts commit 8c03e3e60d46da71708c4a0e4dacf46a0179d18d.
