UPSTREAM: dm: core: Do not stop uclass iteration on error

When probing a device fails NULL pointer is returned, and following
devices in uclass list cannot be iterated. Skip to next device on error
instead.

With that the only condition under which these simple iteration
functions return error is when the dm is not initialized at uclass_get
time. This is not all that interesting, change return type to void.

UPSTREAM: dm: core: Switch uclass_*_device_err to use uclass_*_device_check

The _err variant iterators use the simple iterators without suffix as
basis.

However, there is no user that uclass_next_device_err for iteration,
many users of uclass_first_device_err use it to get the first and
(assumed) only device of an uclass, and a couple that use
uclass_next_device_err to get the device following a known device in the
uclass list.

While there are some truly singleton device classes in which more than
one device cannot exist these are quite rare, and most classes can have
multiple devices even if it is not the case on the SoC's EVB.

In a later patch the simple iterators will be updated to not stop on
error and return next device instead. With this in many cases the code
that expects the first device or an error if it fails to probe may get
the next device instead. Use the _check iterators as the basis of _err
iterators to preserve the old behavior.

It is sometimes useful to find a device in a uclass using only its driver

dm: core: add kernel dtb version 2 mechanism support

The V2 mechanism:
- both of U-Boot and kernel's *ALL* devices are exist in dm tree.
- put the necessary U-Boot devices in the head of device uclass list.
- the both existence policy don't require phandle fixup any more.
- it is for the next generation(rk3588 ...) or necessary platforms.
- traverse u-boot fdt phandle if not found in kernel fdt, because
the U-Boot framework gets phandle by of_root(from fdt) but not dm_root(from dm).
The V1 mechanism(legacy):
- U-Boot: only some necessary U-Boot devices(storage, crypto...) in dm tree.
- kernel: all the devices(except the U-Boot only) in dm tree.

The commit (bd3ad955a3 scripts/dtc: phandle index start from 0x1000000) is
necessary for this v2 mechanism.
