Additional runtime check for DTB presence in BL2
In Mbed TLS shared heap code, an additional sanity check is introduced in BL2. Currently, when BL2 shares heap with BL1, it expects the heap info to be found in the DTB. If for any reason the DTB is missing, BL2 cannot have the heap address and, hence, Mbed TLS cannot proceed. So, BL2 cannot continue executing and it will eventually crash. With this change we ensure that if the DTB is missing BL2 will panic() instead of having an unpredictable crash.
