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.

+Subject: [PATCH 330/331] MIPS: Malta: Mark kernel code and kernel data
+ segments as BOOT_MEM_RAM.
+
+Kexec-tools requires those segments listed as "System RAM" in
+/proc/iomem, otherwise, an error message of "Invalid memory segment"
+will be emitted when trying to load the ELF kernel image.
