The content dm_ofnode_pre_reloc() is identical with ofnode_pre_reloc()
defined in drivers/core/ofnode.c and used only three times:
- drivers/core/lists.c:lists_bind_fdt()
- drivers/clk/at91/pmc.c::at91_clk_sub_device_bind
- drivers/clk/altera/clk-arria10.c::socfpga_a10_clk_bind

So this function dm_ofnode_pre_reloc can be removed and replaced
by these function calls by ofnode_pre_reloc().

This adds a message to lists_bind_fdt when it skips initializing a device
pre-relocation. I've had a couple errors where a device didn't initialize
properly because one of its dependencies was missing.

The pr_debug() functions do not response to setting the log level and in
fact have their own separate log level. Use U-Boot logging instead.

Perhaps we should make these options redirect to log_debug(), etc.?

Currently the comments of several APIs (eg: dm_init_and_scan()) say:

@pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC
flag. If false bind all drivers.

The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt
documents the same that both device tree properties and driver flag
are supported.

However the implementation only checks these special device tree
properties without checking the driver flag at all. This updates
lists_bind_fdt() to consider both scenarios.

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.

As we discussed before in ML, dm_dbg() causes undefined reference
error if #define DEBUG is added to users, but not drivers/core/util.c

We do not need this macro because we can use pr_debug() instead, and
it is pretty easy to enable it for the DM core by using ccflags-y.

This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing.  Follow the naming
of_get_property() from Linux.

The return type (const u32 *) is wrong.  DT property values can be
strings as well as integers.  This is why of_get_property/fdt_getprop
returns an opaque pointer.

Adjust this function to us an ofnode instead of an offset, so it can be
used with livetree. This involves updating all callers.
