This change adds a new kind of core dump mechanism which instead of dumping
entire program segments of the firmware, dumps sections of the remoteproc
memory which are sufficient to allow debugging the firmware. This function
thus uses section headers instead of program headers during creation of the
core dump elf.

elf32 and elf64 mainly differ by their types. In order to avoid
copy/pasting the whole loader code, generate static inline functions
which will access values according to the elf class. It allows to
keep a common loader basis.
In order to accommodate both elf types sizes, the maximum size for a
elf header member is chosen using the maximum value of the field for
both elf class.
