Using the TPL method for nand boot by sram was already
supported. Here add some code for mpc85xx ifc nand boot.
- For ifc, elbc, esdhc, espi, all need the SPL without
section .resetvec.
- Use a clear function name for nand spl boot.
- Add CONFIG_SPL_DRIVERS_MISC_SUPPORT to compile the fsl_ifc.c
in spl/Makefile;

changes for v2:
- seperate public code and c29xpcie board code
- add ifc support
changes for v3:
- remove the redundant plus
- ifc support use CONFIG_SPL_DRIVERS_MISC_SUPPORT
changes for v4:
- modify the nand_load function
- add comments in README.SPL
changes for v5:
-none
changes for v6:
- modify the readme file for the include lib file

have you checked the compilation warning for non TPL framework?
