[ARM] 5027/1: Fixed random memory corruption on pxa suspend cycle.
Each time a pxa type cpu went in suspend, a portion of kmalloc memory was corrupted. The issue was an incorrect length allocation introduced by the commit 711be5ccfe9a02ba560aa918a008c31ea4760163 for the save registers array (=> overflow).
