Subject: [PATCH RFC DO NOT MERGE] arm64: dts: qcom: sm8750-mtp: Add WiFi and Bluetooth
MTP8750 rev 2.0 (power grid v8) boards come as two different variants
with different WiFi chips: WCN7850 and WCN786x. WCN7850 is already
supported by the kernel, but WCN786x is not. Both of the board variants
are considered newest revisions and the difference is only in MCN
numbers and internal codenames.
Add WCN7850 WiFi and Bluetooth to the MTP8750, stating that this DTS
represents the WCN7850 variant. The S5F regulator should operate at
0.85 V, thus adjust lower constraint and its label.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

Posting as RFC because it depends on unpublished PCI DTS patches thus it
cannot be merged/build.
Bluetooth not yet tested, because my user-space is incomplete. I am
working on fixing this but anyway I don't expect issues since it is
exactly the same as previous SoCs.
