This is an alignment with Linux DT files that have been merged in
stm32 tree [1], and will be in Linux 6.7.
The /omit-if-no-ref/ in overlay files are now removed, as already in
pinctrl files.

To keep (as much as possible) alignment with Linux DT, move the
/omit-if-no-ref/ keywords to DT overlay files (fdts/stm32mp1*-bl*.dtsi).
This also ease checks for ST tools.

Use /omit-if-no-ref/ keyword in DT to remove extra device nodes only
when they are not used / not referenced.
If the board device tree only defines subnodes, dtc does not consider it
as usage, you have to specifically mention device's phandle, e.g.:
\ {
i2c6-phandle = <&i2c6>;
};
or in aliases section
aliases {
i2c6 = &i2c6;
};

With the /omit-if-no-ref/ keyword in DT, the non-referenced nodes
are just removed. This allows reducing the size of device tree blobs.
Setting it before pins node allows a size reduction of more than 2kB.
The corresponding nodes can also be removed from BL2 and BL32 DT
overlays.

The code managing legacy boot (without FIP) that was under
STM32MP_USE_STM32IMAGE flag is remove.

Add the stm32mp1 CoT description file. Include the TRUSTED_BOARD_BOOT
entry in the platform device tree file.
Add the missing public root key reference for stm32mp15 and the
encryption key reference for stm32mp13.

Due to commit updating kernel yaml file [1], we need to align TF-A DT
files to what is done in kernel.

If a board declares an mmc1 alias in its DT and is compiled without flags
STM32MP_EMMC or STM32MP_SDMMC, the DT will fail to build.
Add /delete-property/ mmc1; to correct this.

Cleanup the BL2 device tree file by removing the nodes for the devices
that are not used to boot, depending on compilation flags.
In SDMMC boot, the gain for the dtb file is about 2.3kB.

BL2 still uses the STM32 header binary format to be loaded from ROM code.
BL32 and BL33 and their respective device tree files are now put together
in a FIP file.
One DTB is created for each BL. To reduce their sizes, 2 new dtsi file are
in charge of removing useless nodes for a given BL. This is done because
BL2 and BL32 share the same device tree files base.
The previous way of booting is still available, the compilation flag
STM32MP_USE_STM32IMAGE has to be set to 1 in the make command. Some files
are duplicated and their names modified with _stm32_ to avoid too much
switches in the code.
