LoongArch: kexec: Print out debugging message if required
When specifying '-d' for kexec_file_load interface, loaded locations of
kernel/initrd/cmdline etc can be printed out to help debug.
Commit eb7622d908a0 ("kexec_file, riscv: print out debugging message if
required") fixes the same issue on RISC-V.
So, remove kexec_image_info() because the content has been printed out
in generic code.
And on Loongson-3A5000, the printed messages look like below:
kexec_file: kernel: 00000000d9aad283 kernel_size: 0x2e77f30
kexec_file(EFI): No LoongArch PE image header.
kexec_file: Loaded initrd at 0x80000000 bufsz=0x1637cd0 memsz=0x1638000
kexec_file(ELF): Loaded kernel at 0x9c20000 bufsz=0x27f1800 memsz=0x2950000
kexec_file: nr_segments = 2
kexec_file: segment[0]: buf=0x00000000cc3e6c33 bufsz=0x27f1800 mem=0x9c20000 memsz=0x2950000
kexec_file: segment[1]: buf=0x00000000bb75a541 bufsz=0x1637cd0 mem=0x80000000 memsz=0x1638000
kexec_file: kexec_file_load: type:0, start:0xb15d000 head:0x18db60002 flags:0x8
