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 us to disable the rfkill feature.
