stm32: Missing LL header files ?

[erwango]

tl;dr: Please run west update

Following merge of use generic LL headers and STM32 generic LL headers for further peripherals, STM32 drivers all make use of "generic LL headers". This changes were made as a solution to Improve STM32 LL HAL usage.

As a consequence, LL headers are now provided by headers files available in hal_stm32 module: https://github.com/zephyrproject-rtos/hal_stm32/tree/master/stm32cube/common_ll/include.

You might see building errors due a misalignment between Zephyr main repo version and the version of your hal_stm32 module. Something like:

zephyrproject/zephyr/drivers/dac/dac_stm32.c:33:18: error: 'LL_DAC_CHANNEL_1' undeclared here (not in a function); did you mean 'LL_ADC_CHANNEL_1'?
33 | #define CHAN(n) LL_DAC_CHANNEL_##n
| ^~~~~~~~~~~~~~~

You can fix this issues using west update.

In order to avoid this kind of desync between zephyr main repo and modules, you can have a look to #28651

Note: Same solution applies to missing st/foo/stm32foobar-pinctrl.dtsi files.
