lib: Add FIT payload support
* Add support for parsing and booting FIT payloads.
* Build fit loader code from depthcharge.
* Fix coding style.
* Add Kconfig option to add compiletime support for FIT.
* Add support for initrd.
* Add default compat strings
* Apply optional devicetree fixups using dt_apply_fixups
Starting at this point the CBFS payload/ can be either SELF or FIT.
Tested on Cavium SoC: Parses and loads a Linux kernel 4.16.3.
Tested on Cavium SoC: Parses and loads a Linux kernel 4.15.0.
Tested on Cavium SoC: Parses and loads a Linux kernel 4.1.52.
