[PATCH 5/6] ARM: nommu: Use VECTORS_BASE for vector copying with !MMU

From: Jonathan Austin <redacted>

When compiling with !CONFIG_MMU the vectors_page pointer does not get
initialised. In the high vectors case, this results in copying to the
wrong address (0x0) and hence a failure to boot.

This patch instead uses CONFIG_VECTORS_BASE as the destination address
when !CONFIG_MMU.
