BACKPORT: dm: core: add ofnode and dev function to iterate on node property

Add functions to iterate on all property with livetree
- dev_read_first_prop
- dev_read_next_prop
- dev_read_prop_by_prop
and
- ofnode_get_first_property
- ofnode_get_next_property
- ofnode_get_property_by_prop

And helper: dev_for_each_property

For example:
struct ofprop property;

dev_for_each_property(property, config) {
value = dev_read_prop_by_prop(&property, &propname, &len);

or:

for (res = ofnode_get_first_property(node, &property);
!res;
res = ofnode_get_next_property(&property))
{
value = ofnode_get_property_by_prop(&property, &propname, &len);
....
}

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.

driver: core: reject all mmc device from kernel

- we always follow the rule: use mmc device from U-Boot;
- avoid alias id on defferent device between U-Boot and kernel,
which the U-Boot is not able to handle(rescue).

Example issue:

// kernel:

mmc1 = "/dwmmc@fe320000";
mmc2 = "/sdhci@fe330000";
};

// U-Boot:
aliases {
mmc0 = "/sdhci@fe330000";
mmc1 = "/dwmmc@fe320000";
};

// Log error:

UPSTREAM: libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
include/libfdt.h -> include/linux/libfdt.h
include/libfdt_env.h -> include/linux/libfdt_env.h

and replaces include directives:
#include <libfdt.h> -> #include <linux/libfdt.h>
#include <libfdt_env.h> -> #include <linux/libfdt_env.h>

dm: core: add ofnode_count_phandle_with_args()

This function is usefull to get phandle number contained
in a property list.
For example, this allows to allocate the right amount
of memory to keep clock's reference contained into the
"clocks" property.

To implement it, either of_count_phandle_with_args() or
fdtdec_parse_phandle_with_args() are used respectively
for live tree and flat tree.
By passing index = -1, these 2 functions returns the
number of phandle contained into the property list.

Add also the dev_count_phandle_with_args() based on
ofnode_count_phandle_with_args()

dm: core: Add functions to obtain node's address/size cells

The of_n_addr_cells() and of_n_size_cells() functions are useful for
getting the size of addresses in a node, but in a few places U-Boot needs
to obtain the actual property value for a node without walking up the
stack. Add functions for this and just the existing code to use it.

Add a comment to the existing ofnode functions which do not do the right
thing with a flat tree.

This fixes a problem reading PCI addresses.
