SMM: Add support for malloc in SMM if using TSEG

This is used by the SPI driver and ELOG.

It requires SMM TSEG and a _heap/_eheap region defined in the
    linker script.  The first time malloc is called in SMM the
    start and end pointers to the heap region will be relocated
    for the TSEG region.

Enable SPI flash and ELOG in SMM and successfully
    allocate memory.  The allocated addresses are verified
    to be sure they are within the TSEG heap region:

smm.elf:00014000 B _eheap
    smm.elf:00010000 B _heap
    TSEG base is 0xad000000

Memory allocated in ELOG:
    ELOG: MEM @0xad018030
