Host (hcd_ci_fs.c):
- Release the speculatively-armed sibling BDT on the NAK path (IN only) as
well as on completion, so a NAKed multi-packet IN no longer leaks a BDT
that stays own=1 and blocks every same-direction pipe. Both paths now go
through a single release_sibling_bd() helper (was a copy-pasted disarm).
- Clear the ENTIRE shared BDT (both directions) on bus reset; clearing only
the IN half left a stale OUT/SETUP descriptor after a disconnect mid-OUT,
blocking the first control transfer on re-enumeration.
- Size bda[] to span the whole BDT (2*2*4) so STAT-indexed access is within
the declared array bounds (was out-of-declared-bounds, benign via union).
Shared (ci_fs_type.h):
- Hoist buffer_descriptor_t and the TOK_PID enum out of the device and host
drivers into the shared header so the identical definitions cannot drift.
Board (kinetis_k):
- Drop a redundant local in board_get_unique_id.
Build-verified: host + kinetis k/kl/k32l + MCX. HIL: frdm_k64f host 2/2
(cdc_msc_hid + device_info); frdm_kl25z device core suite green with the
relocated definitions.

hcd_ci_fs shares a single BDT set across all pipes. prepare_packets()
speculatively arms the sibling (odd^1) BDT of a multi-packet transfer so it
can ping-pong without NAKs. When such a transfer ends early (a short IN
packet) or fails, the still-owned sibling was never released, permanently
blocking the shared BDT for every other pipe.
This deadlocked a 2nd device enumerating behind a hub while another device
issued descriptor reads (host/device_info with CDC+MSC): the MSC's control
transfers could never acquire the BDT, so it never got Set Address.
Release the sibling in process_tokdne()'s completion path, but ONLY for a
multi-packet transfer (length > max_packet_size): a single-packet transfer
never arms a sibling, so that BDT slot may legitimately belong to another
pipe's in-flight transfer and must not be disturbed (doing so unconditionally
corrupts concurrent transfers, e.g. the CDC bulk-IN vs MSC enum in
host/cdc_msc_hid).
Mirrors the equivalent device-side fix in dcd_ci_fs.c; the host needs the
multi-packet guard because its BDT set is shared across pipes.
Verified on frdm_k64f (HIL): host/device_info now enumerates both CDC+MSC
behind a hub, host/cdc_msc_hid still mounts the MSC (no regression).

A multi-packet OUT transfer speculatively arms both even/odd BDTs to avoid
NAK. When the host ends the transfer early with a short packet, the sibling
BDT was left armed (own=1), desyncing the even/odd ping-pong so the next OUT
packet landed at buffer+max_packet_size instead of buffer and the stack read
stale data. Disarm the sibling on completion.
Fixes device/mtp on Kinetis (GetDeviceInfo command was received into the wrong
buffer half -> hang). Pre-existing (MSC only arms single-packet command
receives so it never hit the double-buffer path). HIL: frdm_kl25z & frdm_k64f
device 13/13.

Complete the khci -> chipidea ci_fs migration that was started for device
(commit d70403f1f "host is not yet"):
- device: switch kinetis_k/kl/k32l (Makefiles + k32l CMake) to dcd_ci_fs.c
- host: add hcd_ci_fs.c (port of hcd_khci.c onto ci_fs_regs_t) and switch all
Kinetis families to it; remove src/portable/nxp/khci entirely
- enable host examples (device_info, cdc_msc_hid) for mcu:KINETIS_K
- README: merge the KL and K32L2 rows into a single "KL, K32L" ci_fs row
hcd_ci_fs.c also fixes two pre-existing host bugs found via HIL on frdm_k64f
(present in the old hcd_khci.c too):
- data toggle was flipped on a NAK in suspend_transfer; a NAK transfers no
data so the toggle must be preserved, else the retried bulk packet is
silently discarded by the device (MSC CBW/CSW hang). See comment in file.
- prepare_packets asserted and dropped a transfer when the single shared BDT
was still owned by an in-flight transfer under concurrent activity; now it
returns busy and resume_transfer defers/retries on the next SOF.
HIL verified on frdm_k64f: device 13/13, host cdc_msc_hid (CDC mount + echo +
MSC mount, through a hub).

- dcd_edpt_stall flushes the primed buffer (ENDPTFLUSH), but the aborted
transfer's dQH overlay can be left ACTIVE with mid-transfer state; the
next prime after clear-halt then resumes the stale overlay instead of
loading the fresh qtd, so post-halt IN reads return mid-buffer data
(usbtest case 13 'buf[32] = 56 (not 0)', with case 18 failing
downstream of the same corruption in the full battery). qhd_start_xfer
now clears overlay.active alongside overlay.halted before linking the
new qtd.
- test/hil(hfp): drop lpcxpresso43s67's device/usbtest skip - the
historical first-case wedge no longer reproduces on this branch, and
with the overlay fix the board runs 30/30 on its Fresco xHCI host
(previously 28/30 with deterministic case 13/18 failures).
mimxrt1064_evk (imxrt dcache path) 30/30 regression-clean.
- docs(hil skill): document the external hifiphile rig - pool
test/hil/hfp.json, SSH-reachable from htpc/ci with no outbound SSH,
exercised by the CI hil-tinyusb (hfp.json) job; never run HIL against
it during development unless the user explicitly asks.
