[PATCH RFC 3/3] arm64: dts: qcom: x1-microsoft-denali: disable WCN7850 hardware rfkill

[Franz <franzelfranzel@gmail.com>]

The WCN7850 hardware rfkill input reads as "radio off" on the Surface
Pro 11, which keeps Wi-Fi hard-blocked. Mark it as unusable.

Tested by adding the property to the installed DTB with fdtput, on
next-20260929 with the matching ath12k change.
