Modifications in tsar_boot:
- Creating new files boot_utils.[c h] containing the memcpy, memset and some
ELF format debug functions
- Introducing assert in the boot_elf_loader to show an error when some of
segments to load conflicts with some of the pre-loader segments
- Cosmetic changes in boot_elf_loader to improve code readibility
- Fixing bug in dcache_buf_invalidate function used by boot_ioc_read when
cache coherence not supported. The condition in the for loop was erroneous.
- Modification in Makefile: The SYSCLK_FREQ parameter is not passed anymore
as a Makefile parameter but it is definesd in the defs_platform.h file
