Description of "ARM: dts: qcom: add and enable both wifi blocks on the IPQ4019"

The change “ARM: dts: qcom: add and enable both wifi blocks on the IPQ4019” introduces changes as follows.

ARM: dts: qcom: add and enable both wifi blocks on the IPQ4019

This patch adds and enables the device-tree definitions for
both qcom,ipq4019-wifi blocks for the IPQ4019.

Support for these have been added into the ath10k driver since:
commit 280e762e9c72 ("ath10k: enable ipq4019 device probe in ahb module")

The binding documentation was added in:
commit a47aaa69de88 ("dt: bindings: add new dt entry for pre calibration in qcom, ath10k.txt")

This has been tested on an ASUS RT-AC58U (IPQ4019),
an AVM Fritz!Box 4040 (IPQ4018), a Compex WPJ428 (IPQ4028)
and a Cisco Meraki MR33 (IPQ4029).
