Update snow's device tree and config to use driver model for sound. Also
update the others as best we can.
Spring does not appear to have audio support in the kernel. The smdk5250
and smdk5420 boards use a wolfson codec which I cannot test with. So the
only boards that is tested and known to work are snow, pit and pi.

For snow the codec is at address 0x11 on the i2c bus, in 7-bit format.
The device tree and code are in 8-bit format (i.e. shifted left one bit).
Fix both. Fix pit in a similar way.

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.

On pit and pi the TPS65090 regulator is connected only to the EC and we
must use a tunnel to get to it. The existing U-Boot support relies on a
special driver. Add a tunnel definition so that the new device-model
TPS65090 driver can be used unmodified.

The kernel uses upper case for I2C unit addresses. Follow the same

The U-Boot device trees are slightly different in a few places. Adjust them
to remove most of the differences. Note that U-Boot does not support the
concept of interrupts as distinct from GPIOs, so this difference remains.
For sandbox, use the same keyboard file as for ARM boards and drop the
host emulation bus which seems redundant.

The ChromeOS EC keyboard is used by various different chromebooks. Peach
pi being the third board in the u-boot tree to use it (snow and peach
pit the other two). Rather then embedding the same big DT node in the
peach-pi DT again, copy the dtsi snippit & bindings documentation from
linux and include it in all 3 boards.
This slightly changes the dt bindings in u-boot:
* google,key-rows becomes keypad,num-rows
* google,key-colums becomes keypad,num-colums
* google,repeat-delay-ms and google,repeat-rate-ms are no longer used
and replaced by hardcoded values (similar to tegra kbc)

Move the exynos SPI driver over to driver model. This removes quite a bit
of boilerplate from the driver, although it adds some for driver model.
A few device tree additions are needed to make the SPI flash available.

We should be consistent about this. The kernel has moved to #include
which breaks error reporting to some extent but does allow us to include
binding files.

The device seems to hang in SPL if the full speed is used when booting from

While the Exynos5420 chip is used in both Smdk5420 and in the Peach-Pit
line of devices, there could be other boards using the same chip, so a
common configuration file is being added (exynos5420.h) as well
as two common device tree files (exynos54xx.dtsi & exynos5420.dtsi).
The peach board as declared in boards.cfg is a copy of smdk5420
declaration. The configuration files are similar, but define different
default device trees, console serial ports and prompts.
The device tree files for smdk5420 and peach-pit inherit from the same
common file.
