Now that the UART driver can enable the required clocks, remove
the hard-coded clock enable. This requires a small re-order
of a couple functions.

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.

In order to use the driver model and clock system to enable UART
clocks from the serial driver, it's necessary to register the UART
clocks. With the helper function to check for imx6qp vs other
variants, the UART can register for both scenarios.

The ECSPI clock has the ability to select between pll3_60m and
osc on the imx6qp, where it's fixed on other variants. Fix this
by adding using a helper function to determine SoC variant and
register the clock accordingly.

The Ouya microconsole is build on Nvidia Tegra 3 (T33) SoC, featuring a
quad-core 1.7 GHz ARM Cortex-A9 CPU and a ULP GeForce GPU, paired with 1GB
of DDR3 RAM and 8GB of internal flash storage. Running a modified Android
4.1 (Jelly Bean) OS with a custom launcher, it aimed for open-source gaming
via a digital storefront.
This implementation is mostly based on upstream Linux device tree and
fragments of work done by previous developers.

Various signal skew values may be set in the device tree for the ksz9131
Ethernet PHY. For example, the RZ/G2L board requires non-default values
for rxc-skew-psec & txc-skew-psec.
This is based on the ksz9131 phy driver in Linux v6.11.

To simply porting phy drivers from Linux to U-Boot, define
phy_set_bits() and phy_clear_bits() functions with a similar API to
those used in Linux.
The U-Boot versions of these functions include the `devad` argument
which is not present in the Linux versions, to keep them aligned with
the other phy functions in U-Boot.

In ravb_probe(), we were missing a couple of things in the error
handling path:
* We must unregister the MDIO bus before freeing the corresponding
struct mii_dev instance to avoid the potential for use-after-free
bugs.
* We must free the resources acquired by clk_get_bulk() even if the
clocks have not yet been enabled.

extlinux / PXE"
Simon Glass <[email protected]> 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
file is always a booti file. Once it is compressed, a check is made to
make sure that it actually is.
Simplify the implementation by adding a new function which returns the
booti image-type if compression is detected.
