patches/driver/bes2600/*-danctnix + arch/arm64/scs-...: rebased on danctnix baseline (#29 redo)

PR #33's per-series mirrors were generated against the bes2600-dkms
cleanups branch (rooted at fe73571) without rebasing onto the
v7.0-danctnix1 kernel baseline. Result: per-commit diffs carried
stale baseline context (e.g. from_timer rather than the new
timer_container_of API), so the cumulative no longer applied cleanly
to ohm's actual base. pkgrel=6 build #1 failed with 'Hunk #3 FAILED'
in Patch D's sta.c.

Fix: in marfrit/bes2600-dkms, create danctnix-sync branch
(fe73571 + drop-in replace bes2600/ with v7.0-danctnix1's
drivers/staging/bes2600/), rebase cleanups onto it as
cleanups-rebased-on-danctnix, manually resolve the resulting conflicts
keeping each commit's intent + the new baseline context, rebase
Patch H accordingly. Format-patch and re-route to the same series-dir
names as PR #33.

Conflict resolution notes:
- 'remove userspace /dev/bes2600 character device interface' commit:
  the chardev wrapper was removed but two utility funcs that danctnix's
  bes2600_btuart.c depends on (bes2600_chrdev_is_bus_error,
  bes2600_chrdev_switch_subsys_glb) were re-added with EXPORT_SYMBOL_GPL.
  bes2600_switch_bt re-added as static (file-local, called only from
  bes2600_chrdev_switch_subsys_glb).
- Patch D (atomicize ba_lock): re-resolved bes2600_ba_timer's
  timer_container_of() vs from_timer() to keep the new API.
- SCS Makefile @@ hunk counts corrected from -9,6 +9,10 to -9,6 +9,11
  (the original was actually wrong; build-via-fuzz was masking it).

Cumulative b2sum: ka-promote ohm now emits
  eb179c03f35a4dbaec2e40036f0033ef04985bb6b14ab22419d68e5caaa5874f...
  (279 554 bytes, 32 patches resolved).

pkgrel=6 built from this manifest + installed on ohm 2026-05-19 ~23:39.
Functional verification: bes2600 + bes2600_btuart both load, Pattern A
0 over fresh boot, wlan0 associates to newton. srcversion
1A919EED0E6DC2478559B17 differs from pkgrel=5's BEB625FA... — the
reconstruction is functionally equivalent (5 GHz working, no
firmware/driver race conditions) but NOT byte-equivalent (the chardev
utility re-add chose different formatting than the original danctnix
code). Byte-equivalence is not a goal; per-series traceability and
working hardware are.

Closes (proper this time): #29.
Refs: #28, #30, #33 (the half-working attempt), #31, #32.
