Rename current assembler implementation of allow_unaligned() to arm11_arch_cp15_allow_unaligned() and add it into arm11.h header, then add C wrapper of allow_unaligned(). This fixes misbehavior when linking U-Boot, where the CPU specific allow_unaligned() implementation was ignored and instead the __weak allow_unaligned() implementation from lib/efi_loader/efi_setup.c was used, which led to "data abort" just before booting Linux via tftp, in efi_dp_from_file() -> path_to_uefi() -> utf16_put() . The problem is triggerd byc7c0ca3767("efi_loader: fix efi_dp_from_file()") . Adding the wrapper fixes the problem.
