BTUSB_QCA_WCN6855 marks the first generation of QCA BT SoCs for which
devcoredump is enabled; all later generations are enabled too. ATH3012
and QCA_ROME are much older chips that predate devcoredump in the
Bluetooth core driver — there is no requirement to enable it for them
and it is not clear whether they even support it.

  Will optimize the commit message in v2.
