Clock patches for u-boot/next This is mostly cleanups/consolidations. clk_free is made to return void, and the CCF wrappers present in almost every CCF clock are consolidated. I would particularly like to have the latter upstream, since there are at least two series adding support for new CCF drivers (imx8mq and imxrt1170) which can benefit from these commits. I had to fix up the last commit since I missed an include for at91. CI: https://source.denx.de/u-boot/custodians/u-boot-clk/-/pipelines/11521
