LoongArch: Add kexec support
Add three new files, kexec.h, machine_kexec.c and relocate_kernel.S to
the LoongArch architecture, so as to add support for the kexec re-boot
mechanism (CONFIG_KEXEC) on LoongArch platforms.
Kexec supports loading vmlinux.elf in ELF format and vmlinux.efi in PE
format.
I tested kexec on LoongArch machines (Loongson-3A5000) and it works as
expected:
$ sudo kexec -l /boot/vmlinux.efi --reuse-cmdline
$ sudo kexec -e
