riscv: Force flat memory model with no-mmu
[ Upstream commit aa2734202acc506d09c8e641db4da161f902df27 ]
Compilation errors trigger if ARCH_SPARSEMEM_ENABLE is enabled for
a nommu kernel. Since the sparsemem model does not make sense anyway
for the nommu case, do not allow selecting this option to always use
the flatmem model.
