Remove Mbed TLS dependency from plat_bl_common.c
Due to the shared Mbed TLS heap optimisation introduced in 6d01a463,
common code files were depending on Mbed TLS specific headers. This
dependency is now removed by moving the default, unoptimised heap
implementation inside the Mbed TLS specific files.
