9042bf6fe4 clk: Update drivers to use -EINVAL
At present some drivers use -ENOSUPP to indicate that an unknown or
unsupported clock is used. Most use -EINVAL, indicating an invalid value,
so convert everything to that.

fb989e0c6c clk: Drop dm.h header file in clk-provider.h
This header file should not be included in other header files. Remove it
and use a forward declaration and un-inlining of dev_get_clk_ptr()
instead.

Fix up the kendryte header files to avoid build errors.

1a198cf886 clk: Add a bypass clock for K210
This is a small driver to do a software bypass of a clock if hardware
bypass is not working. I have tried to write this in a generic fashion, so
that it could be potentially broken out of the kendryte code at some future
date. For the K210, it is used to have aclk bypass pll0 and use in0 instead
so that the CPU keeps on working.
