Add clk_resolve_parent_clk() to resolve parent clock udevice name
based on clock-names DT property. This is used in SoC clock drivers
to look up the clock name in clock tables, which matches a clock
name in DT clock-names property, and convert it into udevice name
which is used by U-Boot clock framework to look up parent clock in
e.g. clk_register() using uclass_get_device_by_name(UCLASS_CLK,

As the code is today, we get a warning about "select" statements on
"choice" options not doing anything. In this case we can easily fix this
by dropping the select line as the following choice statement handles
things correctly. We also drop the "default false" line as false / n is
the default.

Depending on the platform, there may be multiple clock sources
required to enable a UART. Use the bulk functions to get and
enable the clocks when the UART probes. This can facilitate
the removal of functions to manually enable the clock.
This is made dependent on CLK_CCF which is used on imx6q,
imx8m[mnqp], several imxrt, imx9. If/when the UART clock
registration is done for older boards, this limitation
could be updated.

Simon Glass <sjg@chromium.org> says:
This series includes some patches related to allowing read_all() to be
used with the extlinux / PXE bootmeths.
These patches were split out from the stb4 series, since it will need to
have additional patches for LWIP, to avoid breaking PXE booting when
LWIP is used.

Add a new netboot_run() function which can be used for simple network
operations, such as loading a file. Put the implementation in an
internal function, used by the existing code.
Place this function into the net/ code, so that it does not need the
command line to be available.
Document which network operations are supported, i.e. a limited subset,
for now.
For the one board which uses lwip, it is not quite clear how to avoid
using the cmdline interface. This will need some discussion.

A compressed booti image relies on the compression-format's header at
the start to indicate which compression algorithm is used.
We don't support this elsewhere in U-Boot, so assume that a compressed

make sure that it actually is.
