In an earlier commit, the riscv-privileged level implementation of
`arch_cpu_idle()` is not included unless `CONFIG_RISCV_HAS_CPU_IDLE` is
enabled.
This commit ensures the option is enabled on all the existing CPUs, thereby
maintaining the existing behavior.
Signed-off-by: Chen Xingyu <hi@xingrz.me>
The current configuration comes with a common implementation of
`arch_cpu_idle()` for the whole riscv-privileged family, utilizing the
`WFI` instruction to place the CPU into a light sleep state, with the
assumption that it will be awakened later by interrupts such as SYSTICK.
However, this approach is not always effective, particularly in scenarios
where the SYSTICK is not a valid wake source.
This commit uses `CONFIG_RISCV_HAS_CPU_IDLE` as the build condition of the
family-level `idle.c`, allowing CPUs that do not enable this option to
fallback to a generic arch-level implementation in
`arch/riscv/core/cpu_idle.c`.

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.
