[PATCH] Bluetooth: hci: Represent advertising report payloads as bytes

[PATCH] Bluetooth: hci: Represent advertising report payloads as bytes

[Kyle Pepper]

Advertising records have variable-length data and cannot form a C
array of flexible structures. Describe the report payloads as bytes
to avoid Sparse warnings without changing their wire layout.

Assisted-by: OpenCode:gpt-6.1-sol sparse

Separate cleanup of warnings inherited from upstream, not a v2 of the
UB500 shared-buffer RFC. The same two "array of flexible structures"
warnings reproduce on that RFC's parent and exact submitted commit.
The public bot report only contains the matching include-file note;
its complete Sparse output was not available.

Testing:
- GCC W=1 C=2: hci_event.o and btusb_main.o, no diagnostics after cleanup.
- Exact submitted UB500 commit plus this cleanup: same clean checks.
- Strict GCC/Clang layout checks and LLVM/32-bit hci_event.o builds pass.
- GCC hci_event .text section is byte-identical before/after cleanup.
- A guest carrying the cleanup passes pairing and both HoG variants
  on baseline BlueZ and each of four independent ASHA topics: 15/15.

This does not change the UB500 quirk or certify an unseen complete
remote Sparse report. No full architecture/configuration build matrix
or physical hearing-aid regression test is claimed.
