docs(stm32mp2): introduce new STM32MP23 family

STM32MP23 is a derivative from STM32MP25. It comes in 3 different lines:
- STM32MP235: Dual Cortex-A35 + Cortex-M33 - 2x Ethernet - 2x CAN FD
              H264 - 3D GPU - AI / NN - LVDS / DSI
- STM32MP233: Dual Cortex-A35 + Cortex-M33 - 2x Ethernet - 2x CAN FD
- STM32MP231: Single Cortex-A35 + Cortex-M33 - 1x Ethernet
