Matthias Weisser d8834a1323 arm: Use optimized memcpy and memset from linux 
Using optimized versions of memset and memcpy from linux brings a quite
noticeable speed (x2 or better) improvement for these two functions.

Here are some numbers for test done with jadecpu

                           | HEAD(1)| HEAD(1)| HEAD(2)| HEAD(2)|
                           |        | +patch |        | +patch |

                           |        |        |        |        |
Copy 1.4MB from NOR to RAM |  134ms |   72ms |  120ms |   70ms |

(1) No dcache
(2) dcache enabled in board_init
*Does not work when dcache is on
