For the TEE and android kernelflinger boot requirements, elf_loader need to support the multiboot protocol. This patch define a memory block to store ELF format VM load params in guest address space. At the same time, prepare the elf cmdline field and memory map for the guest kernel.

The elf images can't be loaded correctly because the elf_loader copy_to_gpa with wrong size. The p_filesz and p_memsz both belong to elf32_prog_entry, this data structure describes segments loaded in ram. p_filesz means size of segment in file and p_memsz means size of segment in memory. ELF loader should copy elf_img to gpa with the size of p_prg_tbl_head32->p_filesz.
