Commit c6a97c42e399 ("hwrng: stm32 - add support for STM32 HW RNG")
was inadequately tested (actually it was tested quite hard so
incompetent would be a better description that inadequate) and does
not compile on platforms with CONFIG_PM set.
Fix this.

Add support for STMicroelectronics STM32 random number generator.
The config value defaults to N, reflecting the fact that STM32 is a
very low resource microcontroller platform and unlikely to be targeted
by any "grown up" defconfigs.
