ARM: 8646/1: mmu: decouple VECTORS_BASE from Kconfig
For MMU configurations, VECTORS_BASE is always 0xffff0000, a macro definition will suffice. For no-MMU, exception base address is dynamically determined in subsequent patches. To preserve bisectability, now make the macro applicable for no-MMU scenario too. Thanks to 0-DAY kernel test infrastructure that found the bisectability issue. This macro will be restricted to MMU case upon dynamically determining exception base address for no-MMU. Once exception address is handled dynamically for no-MMU, VECTORS_BASE can be removed from Kconfig.
