dts: Add power-amplifier properties to STM32WL boards/modules

Browse source 
The newly added "power-amplifier-output" property for STM32WL SubGHz
radio nodes is mandatory.

Add the property to all affected modules and boards with the
appropriate value for the factory-default hardware configuration.

Add the "rfo-XX-max-power" properties to all affected modules and
boards with the appropriate value for the hardware configuration.
