"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.

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

called the TI System Control Interface (TI SCI) protocol.
This patch adds a clock driver that communicates to the system

The drivers are based on Linux driver by Gregory Clement.
The TBG clocks support only the .get_rate method.
- since setting rate is not supported, the driver computes the rates
when probing and so subsequent calls to the .get_rate method do not
read the corresponding registers again
The peripheral clocks support methods .get_rate, .enable and .disable.
- the .set_parent method theoretically could be supported on some clocks
(the parent would have to be one of the TBG clocks)
- the .set_rate method would have to try all the divider values to find
the best approximation of a given rate, and it doesn't seem like
this should be needed in U-Boot, therefore not implemented
