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 S4D and S5F regulators should
operate at 0.85 V, thus adjust lower constraint and regulator name.
