On x86-64 we really only support CONFIG_SPARSEMEM; there is nothing users
can select. So enable the memory model selection (via
CONFIG_ARCH_SELECT_MEMORY_MODEL) only if both, SPARSEMEM and FLATMEM are
possible, which isn't the case on x86-64.

x86/Kconfig: Select ARCH_SELECT_MEMORY_MODEL only if FLATMEM and SPARSEMEM are possible
x86-64 supports only CONFIG_SPARSEMEM; there is nothing users can select.
So enable the memory model selection (via CONFIG_ARCH_SELECT_MEMORY_MODEL)
only if both, SPARSEMEM and FLATMEM are possible, which isn't the case
on x86-64.
