Subject: [PATCH v5 2/7] dt-bindings: wireless: ieee80211: Add
 disable-rfkill property

From: Jérôme de Bretagne <jerome.debretagne@...il.com>

For some devices, Wi-Fi is entirely hard blocked by default making
the Wi-Fi radio unusable, except if rfkill is disabled as expected
on those models.

Commit c6a7c0b09d5f ("wifi: ath12k: Add Support for enabling or
disabling specific features based on ACPI bitflag") added a way to
support features set via ACPI, including the DISABLE_RFKILL bit.

Add a disable-rfkill property to expose the DISABLE_RFKILL bit
equivalent for devices described by a Devicetree instead of ACPI.
