RISC-V: Move all address space definition macros to one place

We get the following compilation error if CONFIG_SPARSEMEM_VMEMMAP is set.

./arch/riscv/include/asm/pgtable-64.h: In function ‘pud_page’:
./include/asm-generic/memory_model.h:54:29: error: ‘vmemmap’ undeclared
(first use in this function); did you mean ‘mem_map’?
 #define __pfn_to_page(pfn) (vmemmap + (pfn))
./include/asm-generic/memory_model.h:82:21: note: in expansion of
macro ‘__pfn_to_page’

 #define pfn_to_page __pfn_to_page
./arch/riscv/include/asm/pgtable-64.h:70:9: note: in expansion of macro
  return pfn_to_page(pud_val(pud) >> _PAGE_PFN_SHIFT);

Fix the compliation errors by moving all the address space definition
macros before including pgtable-64.h.

Fixes: 8ad8b72721d0 (riscv: Add KASAN support)
