ath10k-firmware: QCA4019 hw1.0: Add Arista W-118 specific BDFs

[Christopher Griffin]

This replaces my mail of earlier today (05:10 UTC), sent from the wrong
address; please use this one.

Hello,

Please add the attached board files for the Arista W-118 to the QCA4019
board-2.bin.

Hardware: the Arista W-118 is a Wi-Fi 5 wall-plate access point built on
the IPQ4019. Its integrated radios are 2.4 GHz 2x2 802.11n and 5 GHz 2x2
802.11ac. Its third radio, a QCA9882 on PCIe, takes its calibration from
the device's ART partition and needs no board file.

Origin: both files come unmodified from the device's stock firmware, read
from the unit's own NAND: /lib/firmware/IPQ4019/hw.1/boarddata_0.bin
(2.4 GHz) and boarddata_1.bin (5 GHz). They are byte-identical to the
QSDK files the stock firmware loads, boardData_1_0_IPQ4019_DK04_2G.bin
and boardData_1_0_IPQ4019_DK04_5G.bin. They differ from the generic
board-2.bin entries for board IDs 20 and 21, hence the variant.

IDs: the radios report board IDs 20 and 21 (from the calibration data at
ART 0x1020 and 0x5020). The device tree sets
qcom,ath10k-calibration-variant = "Arista-W118", so ath10k requests:

  bus=ahb,bmi-chip-id=0,bmi-board-id=20,variant=Arista-W118  (2.4 GHz)
  bus=ahb,bmi-chip-id=0,bmi-board-id=21,variant=Arista-W118  (5 GHz)

md5sums:

  ff636d18bf9c6fd848009860b90ec460
bus=ahb,bmi-chip-id=0,bmi-board-id=20,variant=Arista-W118.bin
  a40c4aabb1c79887a343dafe3bd731da
bus=ahb,bmi-chip-id=0,bmi-board-id=21,variant=Arista-W118.bin

Tested on a W-118 with OpenWrt main (kernel 6.18.55, ath10k-ct): ath10k
loads both, and both radios come up as access points, on 2.4 GHz and on
5 GHz (VHT80). The device support is openwrt/openwrt#26028 (and the same files
are in openwrt/firmware_qca-wireless#179).

Thanks,
Christopher Griffin
