ARM: 8572/1: nommu: change memory reserve for the vectors
Commit 19accfd3 (ARM: move vector stubs) moved the vector stubs in an additional page above the base vector one. This change wasn't taken into account by the nommu memreserve. This patch ensures that the kernel won't overwrite any vector stub on nommu.
