bootm: Pass SMP core ID and DTB address for ELF-formatted kernels

When booting RISC-V ELF-formatted kernel images (IH_TYPE_KERNEL + IH_OS_ELF),
explicitly pass SMP hart ID (via a0/argc) and DTB address (via a1/argv)
to comply with modern SMP-enabled kernels' boot protocol requirements.
See https://www.kernel.org/doc/html/latest/arch/riscv/boot.html#register-state
