board_r - fixup functions table after relocation
This is only required for "PIC" relocation and doesn't apply to modern "PIE" relocation which does data relocation as well as code. "init_sequence_r" is just an array that consists of compile-time adresses of init functions. Since this is basically an array of integers (pointers to "void" to be more precise) it won't be modified during relocation - it will be just copied to new location as it is. As a consequence on execution after relocation "initcall_run_list" will be jumping to pre-relocation addresses. As long as we don't overwrite pre-relocation memory area init calls are executed correctly. But still it is dangerous because after relocation we don't expect initially used memory to stay untouched.
