fit: Refactor config node handling
This patch makes some minor refactoring to the way the FIT parser handles config nodes. A lot of this code was written in the dawn age of depthcharge when its device tree library wasn't as well-stocked yet, so some of it can be rewritten nicer with more high-level primitives. There's no point in storing both the string name and the actual FDT node of a FIT image node separately, since the latter also contains the former, so remove that. Also eliminate code for the case of not having an FDT (which makes no sense), and move some more FDT validity/compat checking into fit_update_compat() (mostly in anticipation of later changes). This patch was adapted from depthcharge's http://crosreview.com/1553456 with a couple of modifications specific to coreboot's custom FIT loading code.
