arm: Update mem* functions to newer versions
The memcpy/memset/memmove assembly implementations have been taken from U-Boot, which originally got them from Linux. I turns out that they are actually not that bad, but they could use an update. This patch pulls in the current Linux upstream versions of those files, removing some old U-Boot cruft such as checking whether the two pointers in a memcpy() are equal (really now?) or side-stepping the R8 register because it was used for special purposes. It also returns to the good old Linux ENTRY/ENDPROC macros since we have them now anyway, and straightens out the W() macro in preparation for unified thumb support.
