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.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

This header was missing a couple of include dependencies when included on its
own.

Because clk-provider use clk_ops, so let's include clk-uclass.h

The generic mux clock code for CCF requires reading the clock multiplexer
value from HW registers. As sandbox by design has readl() as no-op it was
necessary to provide this value in the other way.
The new field in the mux structure (accessible only when sandbox is run)
has been introduced for this purpose.

This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.
The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the
device tree.
One needs to pay attention to the comments indicating necessary for U-Boot's
driver model changes.
If needed, the code can be extended to support the "set" part of the clock
management.

This file now stores the dev_get_clk_ptr() wrapper on the dev_get_uclass_priv()
function.
