Modified relocate_kernel() doesn't return new kernel's entry point but the random_offset. In this way we share the start_kernel() processing with the normal kernel, which avoids calling 'jr a0' directly and allows some other operations (e.g, kasan_early_init) before start_kernel() when KASLR (CONFIG_RANDOMIZE_BASE) is turned on.
