mbedtls: Don't use tf_snprintf if option not defined
If `MBEDTLS_PLATFORM_SNPRINTF_ALT` isn't used, the function `mbedtls_platform_set_snprintf()` isn't defined. In case a platform uses a different mbed TLS configuration file than the one provided by the Trusted Firmware, and it doesn't define the mentioned build option, this will result in a build error. This patch modifies the initialization code so that `mbedtls_platform_set_snprintf()` is only used if `MBEDTLS_PLATFORM_SNPRINTF_ALT` is defined, allowing platforms to use it or not depending on their needs.
