Subject: [PATCH] testing! arm64: dts: qcom: decrease WiFi antenna regulator
 minimum to 3.0V

From: David Heidelberg <david@...t.cz>

Downstream defines minimal voltage as 3.0 V, while when OnePlus 6 was
introduced to Linux mainline, the value was fixed to maximum 3.3V.

Tested for ~ 1 month. Seems to work well, no visible issues anywhere.
