For MMU configurations, VECTORS_BASE is always 0xffff0000, a macro
definition will suffice.
Once exception address is handled dynamically for no-MMU also (this
would involve taking care of region setup too), VECTORS_BASE can be
removed from Kconfig.

Though there was no build error without inclusion of asm/memory.h, to
be on the safer side it has been added, to reduce chances of build
breakage in random configurations.
