lib: Add FIT payload support

Browse Source 
* 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.
