LoongArch: Add preparatory infrastructure for kexec_file

Add some preparatory infrastructure:
- Add command line processing.
- Add support for loading other segments.
- Other minor modifications.

This initrd will be passed to the second kernel via the command line
'initrd=start,size'.

The 'kexec_file' command line parameter indicates that the kernel is
loaded via kexec_file.
