Add the clock driver for the rk3066 platform.
Derived from the rk3288 and rk3188 driver it
supports only a bare minimum to bring up the system
to reduce the TPL size for:
SDRAM clock configuration.
The boot devices NAND, EMMC, SDMMC, SPI.
A UART for the debug messages (fixed) at 115200n8.
A SARADC for the recovery button.
A TIMER for the delays (fixed).
There's support for two possible frequencies,
the safe 600MHz which will work with default pmic settings and
will be set to get away from the 24MHz default and
the maximum of 1.416Ghz, which boards can set if they
were able to get pmic support for it.
After the clock tree is set during the TPL probe
there's no parent update support.
In OF_REAL mode the drivers ns16550.c and dw-apb-timer.c
obtain the (fixed) clk_get_rate from the clock driver
instead of platdata.
The rk3066 cru node has a number of assigned-clocks properties
that call the .set_rate() function. Add them to the list so that
they return a 0 instead of -ENOENT.

In Linux IMX and IMXRT use the device tree to hold the anatop address.
The anatop is used in clock drivers as it controls the internal PLLs
This will move the macro from asm/arch-imxrt to the device tree.
This presumably should also be done with the other IMX boards as well.

Most callers of this function do not check the return value, and it is
unclear what action they should take if it fails. If a function is freeing
multiple clocks, it should not stop just because the first one failed.
Since the callbacks can no longer fail, just convert the return type to
void.

When freeing a clock there is not much we can do if there is an error, and
most callers do not actually check the return value. Even e.g. checking to
make sure that clk->id is valid should have been done in request() in the
first place (unless someone is messing with the driver behind our back).
Just return void and don't bother returning an error.

"kendryte" is the marketing name for the K210 RISC-V SoC produced by
Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210"
vendor,SoC compatibility string format in the device tree files and
use the SoC name for file names.
With these changes, the device tree files are more in sync with the
Linux kernel DTS and drivers, making uboot device tree usable by the
kernel.

Changes devm_scmi_process_msg() first argument from target parent device
to current SCMI device and lookup the SCMI agent device among SCMI device
parents for find the SCMI agent operator needed for communication with
the firmware.
This change is needed in order to support CCF in clk_scmi driver unless
what CCF will fail to find the right udevice related to exposed SCMI
clocks.
This patch allows to simplify the caller sequence, using SCMI device
reference as parameter instead of knowing SCMI uclass topology. This
change also adds some protection in case devm_scmi_process_msg() API
function is called for an invalid device type.

It is safe to check if the uclass id on the device is UCLASS_CLK
before to call the clk_ functions, but today this comparison is
not done on the device used in API: clkp->dev->parent
but on the device himself: clkp->dev.
This patch corrects this behavior and tests if the parent device
is a clock device before to call the clock API, clk_enable or
clk_disable, on this device.

The optional varients of clk_get_* functions are just simple wrappers.
Reduce code size a bit by inlining them. On platforms where it is not used
(most of them), it will not be compiled in any more. On platforms where
they are used, the inlined branch should not cause any significant growth.

This reverts commit 92f1e9a4b31c0bf0f4f61ab823a6a88657323646.
The aforementioned patch causes massive breakage on all platforms which
have 'assigned-clock' DT property in their DT which references any clock
that are not supported by the platform clock driver. That can easily
happen either in SPL, or because the clock driver is reduced. Currently
it seems all iMX8M are affected and fail to boot altogether.

In order to finish moving this symbol to Kconfig for all platforms, we
need to do a few more things. First, for all platforms that define this
to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to
CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails
also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk()
and updating a few preprocessor tests.
With that done, all platforms that define a value here can be converted
to Kconfig, and a fall-back of zero is sufficiently safe to use (and
what is used today in cases where code may or may not have this
available). Make sure that code which calls this function includes
<clock_legacy.h> to get the prototype.
