Subject: [PATCH v5 7/7] wifi: ath12k: Add support for disabling rfkill via
 devicetree

From: Dale Whinham <daleyo@...il.com>

Some devices (e.g. Microsoft Surface Pro 11) indicate that the rfkill
feature should be disabled by means of an ACPI bitflag.

If ACPI is not being used (i.e. booting using a devicetree) then this
property will not be read and therefore rfkill may be enabled and
the ath12k will be hard-blocked with no way to disable it.

Add a devicetree property that allows to disable the rfkill feature.
