4051c400c5 Correct SPL uses of SANDBOX_CLK_CCF
This converts 12 usages of this option to the non-SPL form, since there is
no SPL_SANDBOX_CLK_CCF defined in Kconfig

560e1e0050 clk: define LOG_CATEGORY for generic and ccf clocks
Define LOG_CATEGORY to allow filtering with log command
for generic clock and CCF clocks.

This patch also change existing printf, debug and pr_ macro
to log_ or dev_ macro.

572c446e98 clk: cosmetic: reorder include files
Reorder include files in the U-Boot expected order:

the common.h header should always be first,
followed by other headers in order,
then headers with directories,
then local files.

It is a preliminary step for next patch.

16bdc85b48 clk: set flags in the ccf registration routines
The top-level framework flags are passed as parameter to the common
clock framework (ccf) registration routines without being used.
Checks of the flags setting added by the patch have been added in the
ccf test.

78ce0bd3ac clk: Always use the supplied struct clk
CCF clocks should always use the struct clock passed to their methods for
extracting the driver-specific clock information struct. Previously, many
functions would use the clk->dev->priv if the device was bound. This could
cause problems with composite clocks. The individual clocks in a composite
clock did not have the ->dev field filled in. This was fine, because the
device-specific clock information would be used. However, since there was
no ->dev, there was no way to get the parent clock. This caused the
recalc_rate method of the CCF divider clock to fail. One option would be to
use the clk->priv field to get the composite clock and from there get the
appropriate parent device. However, this would tie the implementation to
the composite clock. In general, different devices should not rely on the
contents of ->priv from another device.

The simple solution to this problem is to just always use the supplied
struct clock. The composite clock now fills in the ->dev pointer of its
child clocks.  This allows child clocks to make calls like clk_get_parent()
without issue.

imx avoided the above problem by using a custom get_rate function with
composite clocks.

61b29b8268 dm: core: Require users of devres to include the header
At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.
