modules: mbedtls: Provide mbedtls_hardware_poll() conditionally

anangl · stephanosio · commit 010730aff6af · 2022-11-22T13:17:43.000+09:00
This is a follow-up to commit c7327f5. Wrap implementation of the `mbedtls_hardware_poll()` function in `#if defined(CONFIG_MBEDTLS_ZEPHYR_ENTROPY)` so that the function is provided only when that option is activated. Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no>
