generic: improve kexec support of MIPS.
- Allow --command-line parameters of kexec-tools be parsed and used by
the kernel.
- For malta machine, mark kernel code and kernel data segments as
"System RAM" instead of "reserved" in /proc/iomem, otherwise
kexec-tools will complain that program segments in ELF kernel file
are invalid.
