Mbed-TLS requires platforms to allocate it a heap for it's own internal
usage. This heap is typically between shared by BL1 and BL2 to conserve
memory.The base address and size of the heap are conveyed from BL1 to
BL2 through the config TB_FW_CONFIG.
This slightly awkward approach necessitates declaring a placeholder node
in the DTS. At runtime, this node is populated with the actual values of
the heap information. Instead, since this is dynamic information, and
simple to represent through C structures, transmit it to later stages
using the firmware handoff framework.
With this migration, remove references to TB_FW_CONFIG when firmware
handoff is enabled, as it is no longer needed. The setup code now relies
solely on TL structures to configure the TB firmware
