Subject: [PATCH 4.9 029/104] ARM: 8635/1: nommu: allow enabling REMAP_VECTORS_TO_RAM

4.9-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 8a792e9afbce84a0fdaf213fe42bb97382487094 ]

REMAP_VECTORS_TO_RAM depends on DRAM_BASE, but since DRAM_BASE is a
hex, REMAP_VECTORS_TO_RAM could never get enabled. Also depending on
DRAM_BASE is redundant as whenever REMAP_VECTORS_TO_RAM makes itself
available to Kconfig, DRAM_BASE also is available as the Kconfig
gets sourced on !MMU.
