zephyr: userspace_helper: do not always build access helpers

kv2019i · kv2019i · commit a153d34f893c · 2026-02-10T17:51:08.000+02:00
Now that we have CONFIG_SOF_USERSPACE_LL, use it to conditionally
drop some of the thread access helpers. Access to mailbox, DAIs
and DMAs is currently only needed if LL thread is run in user-space.
Leave these out if SOF is built for LL thread scheduling in kernel
space.
