Add DT binding for STM32WB09 SoC TRNG. Signed-off-by: Mathieu Choplain <mathieu.choplain@st.com>
Add driver for TRNG of STM32WB09 SoC. Other SoCs of the STM32WB09 series are not supported for now. Signed-off-by: Mathieu Choplain <mathieu.choplain@st.com>
Add Device Tree node corresponding to STM32WB0 series RNG. The WB09-specific TRNG node is also added by this commit. Signed-off-by: Mathieu Choplain <mathieu.choplain@st.com>
Add device tree overlay to test so that it can run on STM32WB09 hardware. Signed-off-by: Mathieu Choplain <mathieu.choplain@st.com>

Add TRNG driver for STM32WB09 line SoCs, and add a test overlay for Nucleo-WB09KE so that correct behavior can be verified.
The RNG node for the whole STM32WB0 line is introduced in DTSI by this PR, but the driver is explicitly prevented from building if enabled on unsupported SoCs (STM32WB05/06/07, which have different hardware).
I'm fine with changing this to a WB09-only node if it sounds cleaner for now.
Tested OK using standard
tests/drivers/entropy/apiand modified version that also verifiesentropy_get_entropy_from_isrand large buffer sizes.
