On some SoCs, depending on the boot device, the MMC clock block may be
left in a weird state by the ROM code, in which no decent clock may be
provided. Reset the related register to make sure a sane MMC clock is
ready for the controller.

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.

The G12B clock controller is almost identical to the G12A and

makes USB work on the Odroid-N2.

First thing we check in meson_clk_set_rate_by_id() is current_rate == rate.
There is not need to check it again.
