Murilo Opsfelder Araujo 58dbe9b373 powerpc/64s: Fix build failure when CONFIG_PPC_64S_HASH_MMU is not set 
The following build failure occurs when CONFIG_PPC_64S_HASH_MMU is not
set:

    arch/powerpc/kernel/setup_64.c: In function ‘setup_per_cpu_areas’:
    arch/powerpc/kernel/setup_64.c:811:21: error: ‘mmu_linear_psize’ undeclared (first use in this function); did you mean ‘mmu_virtual_psize’?
      811 |                 if (mmu_linear_psize == MMU_PAGE_4K)
          |                     ^~~~~~~~~~~~~~~~
          |                     mmu_virtual_psize
    arch/powerpc/kernel/setup_64.c:811:21: note: each undeclared identifier is reported only once for each function it appears in

Move the declaration of mmu_linear_psize outside of
CONFIG_PPC_64S_HASH_MMU ifdef.

After the above is fixed, it fails later with the following error:

    ld: arch/powerpc/kexec/file_load_64.o: in function `.arch_kexec_kernel_image_probe':
    file_load_64.c:(.text+0x1c1c): undefined reference to `.add_htab_mem_range'

Fix that, too, by conditioning add_htab_mem_range() symbol to
CONFIG_PPC_64S_HASH_MMU.
