documentation: dev-manual, bsp-guide, kernel-manual - kernel workflow

The kernel workflow section was re-written to reflect that the
kernel appendix has been removed.  Also, changes to the flow in
general no longer make reference to the bare clone and the copy
of the bare clone as a method used to modify the kernel.

Many links were modified in other manuals as well.
