Supporting Stop1 mode while BLE RF is enabled requires some specific
adaptation and usage of STM32WBA Cube BLE controller scm API.
scm (Secure clock manager) is in charge of switching clock depending
on RF status and should be informed of PM stop modes scheduling.

Add a new Kconfig option that has to be selected by SoCs providing PM
hooks. This option will be now required to enable CONFIG_PM. Before this
change, CONFIG_PM could always be enabled, regardless of SoC providing
any kind of low-power support.
