[PATCH] arm64: dts: qcom: sdm845-db845c: add wifi variant property

[Dmitry Baryshkov]

Dragonboard845c doesn't have board-specific board-id programmed, it uses
generic 0xff. Thus add the property with the 'variant' of the
calibration data.

Note: the driver will check for the calibration data for the following
IDs, so older board-2.bin files that were distributed as a part of
Linaro releases will continue to work.

- 'bus=snoc,qmi-board-id=ff,qmi-chip-id=30214,variant=Thundercomm_DB845C'
- 'bus=snoc,qmi-board-id=ff,qmi-chip-id=30214'
- 'bus=snoc,qmi-board-id=ff'

For the reference, the board is identified by the driver in the
following way:

ath10k_snoc 18800000.wifi: qmi chip_id 0x30214 chip_family 0x4001 board_id 0xff soc_id 0x40030001
ath10k_snoc 18800000.wifi: qmi fw_version 0x2009856b fw_build_timestamp 2018-07-19 12:28 fw_build_id QC_IMAGE_VERSION_STRING=WLAN.HL.2.0-01387-QCAHLSWMTPLZ-1
