[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).
