[nrf52840] prevent linker from dicarding strong nrf5CryptoInit implementation (#2899)

Browse Source 
Linker will discard libmbedcrypto_a-cc310_mbedtls.o when searching
mbedTLS library, if it finds weak implementation of
nrf5CryptoInit/Deinit before strong ones. Adding additional
symbols to this file will prevent this behavior and make linker
to search libmbedcrypto_a-cc310_mbedtls.o even after weak
implementations are found.
