This set of patches add extended functionalities for stm32 rng
driver.
Patch #1 includes a reset during probe to avoid any error status
which can occur during bootup process and keep safe rng integrity.

Patch #3 adds a new property to manage the clock error detection
feature which can be disabled on specific target.

Patch #5 rework the timeout calculation for read value that was
previously defined based on loop operation and is now based on
timer.
