[PATCH v2 1/1] ath10k: add option for chip-id based BDF selection

[Abhishek Kumar]

In some devices difference in chip-id should be enough to pick
the right BDF. Add another support for chip-id based BDF selection.
With this new option, ath10k supports 2 fallback options.

The board name with chip-id as option looks as follows
board name 'bus=snoc,qmi-board-id=ff,qmi-chip-id=320'

Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.2.2-00696-QCAHLSWMTPL-1
Tested-on: QCA6174 HW3.2 WLAN.RM.4.4.1-00157-QCARMSWPZ-1
