[U-Boot] [PATCH v3 9/9] cmd: move CONFIG_CMD_CLK to Kconfig

[Philipp Tomsich]

The CMD_CLK configuration allows the clk-command today (having only
the 'clk dump' action for printing the clock configuration using a
per-SoC weak function).

It is currently only selected by ZYNC and PIC32. To make it easier
to use this command for other platforms and to select it via defconfig,
we are moving it into Kconfig.

Given that this is a debug/maintainer command, the default was chosen
as 'n' and thus should cause no warning messages to board that still
enable it in their respective header files.
