[ 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.
