[nrf fromtree] soc: nrf53: Warn if workaround for anomaly 160 cannot …

…be applied This is a follow-up to commit fe3b97a. Add a cmake warning issued when the workaround for the nRF5340 anomaly 160 cannot be applied because the application is configured with no system clock. Signed-off-by: Andrzej Głąbek <[email protected]> (cherry picked from commit 4e197b7)

+ Indicates that the workaround for the anomaly 160 that affects

+ This option is enabled by default for the Application MCU when
+ DC/DC mode is enabled for the VREGMAIN or VREGRADIO regulator
+ and always for the Network MCU.
+ If this option is enabled, but the workaround cannot be applied,
+ because the system clock is disabled, a related cmake warning is
