[ARM] 4838/1: Fix kexec for SA1100 machines

Browse Source 
This patch sets KEXEC_CONTROL_MEMORY_LIMIT to (-1)UL. As the value is
compared with physical addresses TASK_SIZE makes no sense. Machines
where the RAM addresses start above TASK_SIZE kexecs eats all memory
and crashes the kernel without this patch.
