doc: releases: document radio binding renames in 4.4

Add migration guide and release notes entries for the radio-related
devicetree binding renames:
- generic-fem-two-ctrl-pins -> radio-fem-two-ctrl-pins
- gpio-radio-coex -> radio-gpio-coex
- tx-high-power-supported -> radio-tx-high-power-supported

Also document the new radio.yaml base binding for generic radio
hardware capabilities.

+=====

+* The following devicetree bindings have been renamed for consistency with the ``radio-`` prefix:
+
+  * :dtcompatible:`generic-fem-two-ctrl-pins` is now :dtcompatible:`radio-fem-two-ctrl-pins`
+  * :dtcompatible:`gpio-radio-coex` is now :dtcompatible:`radio-gpio-coex`
+
+* A new :dtcompatible:`radio.yaml` base binding has been introduced for generic radio hardware
+  capabilities. The ``tx-high-power-supported`` property has been renamed to
+  ``radio-tx-high-power-supported`` for consistency.
+
+* Device trees and overlays using the old compatible strings must be updated to use the new names.
