By default U-Boot reserve overlay sizee with 4KB padding, sometime it is
not enought and it is normal.
The caller NEED to reserved enought memory before to apply overlay
by usisng the <extrasize> parameter.
fdt resize [<extrasize>]
- Resize fdt to size + padding to 4k addr + some optional <extrasize> if needed
A correct value cannot be proposed (it is depending of the overlay size)
but at least you must reserved the size of the loaded overlay dtbo file
=> ${filesize} (this variable automatically updated after a load command)

In order to manage multiple defconfig definition for same UBOOT_CONFIG
label, to address subset of devicetree files form UBOOT_DEVICETREE list, we
implement new functionality to provide UBOOT_CONFIG labels with format:
UBOOT_CONFIG += "<uboot_config_label>_<uboot_devicetree_filter_pattern>"
As soon as UBOOT_CONFIG label contains '_' chars, we split it into two
separate parts:
- first one for UBOOT_CONFIG label (used as suffix on binary name)
- second one for pattern (used as filter on devicetree name)

To manage overlay device tree on U-Boot via boot.scr script:
- add an overlay entry on extlinux.conf without FDT or FDTDIR
- create a directory named 'overlays' on boot directory
- populate 'overlays' with the device tree overlay
- create a file named overlays.txt on overlays directory
- syntax of overlays.txt:
overlay=aa bb cc dd
- aa, bb, cc, dd correspond to a device tree name file (without extension)
present on /overlays/ directory
/overlays/aa.dtbo
/overlays/bb.dtbo
/overlays/cc.dtbo
/overlays/dd.dtbo

- Split properly between tf-a-stm32mp and tf-a-stm32mp-ssp.
- Remove use of PV_class-devupstream: no more needed since we avoid using
SRCPV inside default PV (this avoid also misalignment with PV when updated).
- Fix missing fragment files for linux-stm32mp when devupstream in use.

This is required as some recipes might depend on the 'u-boot' recipe,
and if this is not present it would pull in the upstream recipe in
oe-core instead.
