* [dm][clk] fixup the work flow of CLK
Add RT_CLK_F_SET_RATE_NO_REPARENT so clock providers can preserv
the currently selected parent during rate changes.
Round and re-read the effective clock rate after parent handling,
skip redundant gate toggles and hardware programming when
the target is already active, and fix error handling for parent-clock allocation failures.

The old CLK is can't link all hardware clock cell in system that the
API of layout such as 'set_parent' can't work as expected.
Some hareware clock cell need some flags to prevent some dangerous behaviors, eg:
When a clock cell is link to the PMU, the SoC will power-down if the cell is
disable.
The new CLK can do it, and make the CLK drivers implemented easier from
TRM/DataSheet.

Problen:
Duplicated definition of group_clk in clk.c and clk.h.
Solution:
Delete the definition in clk.c and keep only the definition
in clk.h.
Also change the name of group_clk to group_driver_clock to
conform to the naming convention of other driver groups.

The originally defined "group_Drivers" should actually
be part of the device-driver component, so
"group_Drivers" is renamed to "group_device_driver".
In this way, the original "group_Device" and
"group_Drivers" are merged into "group_device_driver".
Adjusted the writing method of doxygen comments in the
driver code to be unified as follows:
```c
* @defgroup group_XXX XXX
* @brief xxxxxx
* @ingroup group_device_driver
```

* doxygen: add prefix for groups
Add "group_" prefix to doxygen group names. This makes
it easier to grep with group name later.
This patch only modifies the groups defined in the pathes
of INPUT of documentation/Doxyfile:
INPUT = . \
../src \
../include \
../components/finsh \
../components/drivers/include/drivers \
../components/drivers/clk \
../components/dfs/dfs_v2/src \
../components/dfs/dfs_v2/include
Other groups are not touched.

* ci: fixed error report when run file_check.py
Such as:
- "please delete extra space at the end of this line."
- "the RT-Thread error code should return negative value. e.g. return
-RT_ERROR"

Accroding to #9947 and #9424, adding doxygen comment for function in .c files and data structure, macro in .h file is a solution.For this pr, I encountered problem following situations.
- rt_clk_unprepare function return value type is different from rt_clk_ops so I change type of rt_clk_unprepare and its dependencies.
- clk_get function may be similar as rt_clk_unprepare but I'm not sure so not modify.
- clk_release implements may be incomplete, so I just marked in comment.

1. Default return OK when input NULL (if is not necessary in device).
2. Support object parse in OFW.
3. Support CLK depends fix auto.
4. Fixup rt_clk_array_prepare_enable and rt_clk_array_disable_unprepare.
