Paul Burton de96ec2a77 OF: Prevent unaligned access in of_alias_scan() ... When allocating a struct alias_prop, of_alias_scan() only requested that it be aligned on a 4 byte boundary. The struct contains pointers which leads to us attempting 64 bit writes on 64 bit systems, and if the CPU doesn't support unaligned memory accesses then this causes problems - for example on some MIPS64r2 CPUs including the "mips64r2-generic" QEMU emulated CPU it will trigger an address error exception. Fix this by requesting alignment for the struct alias_prop allocation matching that which the compiler expects, using the __alignof__ keyword.
