Subject: [PATCH 1/2] ARM: remove memmove from boot/compressed/string.c

This patch removes the memmove function from boot/compressed/string.c
- This definition conflicts with the one in lib/decompress_unxz.c
  This change is required to support xz compression on ARM.
- memmove is not used in any of the other decompressors
  in lib/decompress_*.c
