include: add missing arch/cpu.h include The sys* ops like sys_clear_bit are indirectly included via arch CPU header. Other stuff like find_msb_set end up included via this header as well. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>

boards: migrate includes to <zephyr/...> In order to bring consistency in-tree, migrate all boards code to the new prefix <zephyr/...>. Note that the conversion has been scripted, refer to zephyrproject-rtos#45388 for more details. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>

init: remove the need for a dummy device pointer in SYS_INIT functions The init infrastructure, found in `init.h`, is currently used by: - `SYS_INIT`: to call functions before `main` - `DEVICE_*`: to initialize devices They are all sorted according to an initialization level + a priority. `SYS_INIT` calls are really orthogonal to devices, however, the required function signature requires a `const struct device *dev` as a first argument. The only reason for that is because the same init machinery is used by devices, so we have something like: ```c struct init_entry { int (*init)(const struct device *dev); /* only set by DEVICE_*, otherwise NULL */ const struct device *dev; } ``` As a result, we end up with such weird/ugly pattern: ```c static int my_init(const struct device *dev) { /* always NULL! add ARG_UNUSED to avoid compiler warning */ ARG_UNUSED(dev); ... } ``` This is really a result of poor internals isolation. This patch proposes a to make init entries more flexible so that they can accept sytem initialization calls like this: ```c static int my_init(void) { ... } ``` This is achieved using a union: ```c union init_function { /* for SYS_INIT, used when init_entry.dev == NULL */ int (*sys)(void); /* for DEVICE*, used when init_entry.dev != NULL */ int (*dev)(const struct device *dev); }; struct init_entry { /* stores init function (either for SYS_INIT or DEVICE*) union init_function init_fn; /* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows * to know which union entry to call. */ const struct device *dev; } ``` This solution **does not increase ROM usage**, and allows to offer clean public APIs for both SYS_INIT and DEVICE*. Note that however, init machinery keeps a coupling with devices. **NOTE**: This is a breaking change! All `SYS_INIT` functions will need to be converted to the new signature. See the script offered in the following commit.
