Fix SUPERH builds that select SYS_SUPPORTS_NUMA but do not select
SYS_SUPPORTS_SMP and SMP.
kernel/sched/topology.c is only built for CONFIG_SMP and then the NUMA
code + data inside topology.c is only built when CONFIG_NUMA is
set/enabled, so these arch/sh/ configs need to select SMP and
SYS_SUPPORTS_SMP to build the NUMA support.
Fixes this build error in multiple SUPERH configs:
mm/page_alloc.o: In function `get_page_from_freelist':
page_alloc.c:(.text+0x2ca8): undefined reference to `node_reclaim_distance'
Fixes: 357d59469c11 ("sh: Tidy up dependencies for SH-2 build.")
Fixes: 9109a30e5a54 ("sh: add support for sh7366 processor")

Thanks for these fixes. All changes look good to me and I'm going to test
them on my SH-7785LCR board on top of 6.3-rc1 and report back. The documentation
changes obviously won't have any impact in this regard.

I have successfully applied, built and booted all patches on my SH7785LCR evaluation
board except for patch #5.
I'll do the review next, then include them in my for-next tree for 6.4.

It seems that we need this change for these configurations as well:
- config CPU_SHX3
- config CPU_SUBTYPE_SH7785
Although I can trigger a build failure for CPU_SUBTYPE_SH7785 only when
setting CONFIG_NUMA=y:
CC net/ipv6/addrconf_core.o
mm/slab.c: In function 'slab_memory_callback':
mm/slab.c:1127:23: error: implicit declaration of function 'init_cache_node_node'; did you mean 'drain_cache_node_node'? [-Werror=implicit-function-declaration]
1127 | ret = init_cache_node_node(nid);
| ^~~~~~~~~~~~~~~~~~~~
| drain_cache_node_node
I would expect this error to be reproducible for CPU_SHX3 as well when
CONFIG_NUMA=y but CONFIG_SMP=n. But for some reason, I am not seeing
the error then.

Can you make this change for config CPU_SUBTYPE_SH7785 as well?
Then the change should be fine.

All applied to sh-linux/for-next now except for patch number 6.
Apologies that it took so long, I'm still learning :-).
