After the transition to DM, only the mx6dl/solo wandboard

Add FIT image support so that all the wandboard variants

When using DM_I2C the speed value supplied to setup_i2c() is not used,
so this code required CONFIG_SYS_MXC_I2C[12]_SPEED to be defined to
compile, but did not actually use them.

Change this so we no longer need to define an unused macro to compile in
DM_I2C mode.  Also make it more clear that they do not control the bus
speed.  Otherwise it is quite easy to mistakenly believe they are used
to set the bus speed.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

Latest wandboard hardware revision is revd1, which brings the following
new features:

- PFUZE100 PMIC
- AR8035 Ethernet PHY
- Upgrade Wifi/BT chip to BCM4339/BCM43430.

The detection mechanism is to probe the PMIC and when it is
found, then the revision of the board is revd1.

As the detection is done via PMIC, we need to print the board version
at a later stage via CONFIG_DISPLAY_BOARDINFO_LATE and also need
to disable CONFIG_DISPLAY_BOARDINFO, which is done much earlier.

Make the necessary adjustments for the AR8035 PHY to work on revd1.

Since commit ce412b79 ("drivers: net: phy: atheros: add separate
config for AR8031") ethernet does not work on mx6sabresd.

This commit correctly assigns ar8031_config() as the configuration
function for AR8031 in the same way as done in the Linux kernel.

However, on wandboard design we need some additional configuration,
such as enabling the 125 MHz AR8031 output that needs to be done
in the board file.

This also aligns with the same method that the kernel performs
the AR8031 fixup in arch/arm/mach-imx/mach-imx6q.c.

As per the AR8031 datasheet:

"For a reliable power on reset, suggest to keep asserting the reset
low long enough (10ms) to ensure the clock is stable and clock-to-reset
1ms requirement is satisfied."

So do as suggested and also add a 100us delay after deasserting the
reset line to guarantee that the PHY ID can be read correctly and the
Atheros 8031 PHY driver can be loaded automatically.

PUE requires PKE to mean something, as do pull values with PUE, so do not
compell users to explicitly use PKE and PUE everywhere. This is also what is
done on Linux and what has already been done for i.MX51.

By the way, remove some unused pad control definitions.

There is no change of behavior.

Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.
