[PATCH 0/6] Bluetooth: btusb: Preparation for upcoming Qualcomm QCC2072 support

[Zijun Hu <zijun.hu@oss.qualcomm.com>]

This series collects the btusb and devcoredump changes required by the
upcoming Qualcomm QCC2072 Bluetooth driver. None of them are QCC2072-
specific: they refactor btusb into a shape that can host vendor-specific
source files, and make a few coredump helpers reusable.

Posting them as a standalone series because the QCC2072 driver itself is
larger and will take longer to review. These prerequisites are small and
self-contained, so they can hopefully be reviewed and merged on their own
in the meantime.

The series contains:
 - coredump: a readable state-name helper and a fixed-size dump header,
   both reused by the vendor driver
 - btusb: an indirect recv_intr() hook, hci_dev-based recv wrappers, a
   shared reset-prepare helper, and a split into btusb_main.c so vendor
   files can be added later

No functional change intended.
