linux-yocto/5.10: fix arm defconfig warnings

A recent fix to the kern-tools promoted some previously unseen
issues to warnings. This commit fixes them by tagging some BT
options as non-hardware so they won't generate warnings if they
don't appear in the final .config. These are sub BT options and
shouldn't warn when/if their controlling option is disabled by
a fragment.
