Subject: [PATCH v2 00/15] pinctrl: stm32: rework SoC package and add STM32MP21

This v2 is a subset of the v1, split-out to simplify the review.
The old patches concerned in v1 where 10/14, 11/14 and 14/14.

This subset:
- obsoletes the numeric values of the property 'st,package' in STM32
  pinctrl and replaces it with a string value. Keeps backward
  compatibility for old DTs;
- updates the DT to use the new values for 'st,package';
- add new packages to STM32MP25;
- add pinctrl driver and bindings for STM32MP21, including the extra
  dependencies of optee and exti nodes;
- on board STM32MP215f-DK, use the pinctrl driver to properly setup
  the UART and add the heartbeat LED.


Changes v1 -> v2 subset:
- rebased on linux-pinctrl branch for-next;
- replace numeric values of property 'st,package' with strings;
- add users of pinctrl driver on board STM32MP215f-DK;
- Link to v1: https://lore.kernel.org/lkml/20241022155658.1647350-1-antonio.borneo@foss.st.com/
