LoongArch: Add ELF binary support for kexec_file

LoongArch: Add ELF binary support for kexec_file

This patch creates kexec_elf_ops to load ELF binary file for
kexec_file_load() syscall.

However, for `kbuf->memsz` and `kbuf->buf_min`, special handling is
required, and the generic `kexec_elf_load()` cannot be used directly.

$ readelf -l vmlinux
...
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
LOAD 0x0000000000010000 0x9000000000200000 0x9000000000200000
0x0000000002747a00 0x000000000287a0d8 RWE 0x10000
NOTE 0x0000000000000000 0x0000000000000000 0x0000000000000000
0x0000000000000000 0x0000000000000000 R 0x8

phdr->p_paddr should have been a physical address, but it is a virtual
address on the current LoongArch. This will cause kexec_file to fail
when loading the kernel and need to be converted to a physical address.

From the above MemSiz, it can be seen that 0x287a0d8 isn't page aligned.
Although kexec_add_buffer() will perform PAGE_SIZE alignment on kbuf->
memsz, there is still a stampeding in the loaded kernel space and initrd
space. The initrd resolution failed when starting the second kernel.

It can be known from the link script vmlinux.lds.S that,
BSS_SECTION(0, SZ_64K, 8)
. = ALIGN(PECOFF_SEGMENT_ALIGN);

It needs to be aligned according to SZ_64K, so that after alignment, its
size is consistent with _kernel_asize.

The basic usage (vmlinux):

1) Load second kernel image:
# kexec -s -l vmlinux --initrd=initrd.img --reuse-cmdline

2) Startup second kernel:
# kexec -e

LoongArch: Add EFI binary support for kexec_file

This patch creates kexec_efi_ops to load EFI binary file for
kexec_file_load() syscall.

The efi_kexec_load() as two parts:
- the first part loads the kernel image (vmlinuz.efi or vmlinux.efi)
- the second part loads other segments (e.g: initrd, cmdline, etc)

Currently, pez (vmlinuz.efi) and pei (vmlinux.efi) format images are
supported.

The basic usage (vmlinuz.efi or vmlinux.efi):

1) Load second kernel image:
# kexec -s -l vmlinuz.efi --initrd=initrd.img --reuse-cmdline

2) Startup second kernel:
# kexec -e

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.
