libpayload: Support unaligned pointers for memset
The optimization of the memset() function introduced by commit dbadb1dd634c8c9419215ade0666a7fb69a4447b (libpayload: Reorder default memcpy, speed up memset and memcmp) is provoking an issue on x86 platform when compiling without the CONFIG_GPL option. GCC is making use of the movdqa instruction to copy words. This instruction can raise a "General Protection Fault Exception" when it is called on a non-aligned address argument.
