Subject: [PATCH] hwrng: stm32 - Fix build with CONFIG_PM

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.

Notes:
    Herbert: This is the diff between v2 and v3 of my STM32 HW RNG
             patch. This is partly reassurance of what has changed
             and also "just in case" you prefer to simply fix the
    	 problem.
