The get_unaligned()/put_unaligned() implementations are more
complex than necessary.
Move everything into one file and use a more compact implementation based
on packed struct access and byte swapping macros.
This patch is based on the Linux kernel commit 803f4e1eab7a
("asm-generic: simplify asm/unaligned.h") by Arnd Bergmann.
