LoongArch: Add kexec/kdump support
Add the 64-bit processing support of the LoongArch architecture. For the time
being, the quick restart function(kexec) is supported. That is, the "kexec -l"
and "kexec -e" commands can be used normally.
At the same time, the crash dump function also supports, "kexec -p" operation
can be successfully performed, and the vmcore file can be generated.
I tested this on LoongArch 3A5000 machine and works as expected,
kexec:
$ sudo kexec -l /boot/vmlinux --reuse-cmdline
$ sudo kexec -e
kdump:
$ sudo kexec -p /boot/vmlinux-kdump --reuse-cmdline --append="nr_cpus=1"
# echo c > /proc/sysrq_trigger
