3919aa1722 ARM: dts: stm32: Add DFU support for DHCOR recovery
This patch configures U-Boot SPL for DHCOR SoM to permit DFU upload of
SPL and subsequent u-boot.itb for recovery or commissioning purposes.

To start U-Boot on DHCOR based board, e.g. Avenger96, proceed as follows:
- Install dfu-util on the host PC (in debian this is package 'dfu-util')

- Power off the Avenger96 board.
- Connect both USB-serial console and USB-OTG microB ports to host PC.
- Switch Avenger96 to USB boot mode -- BOOT0..2 switches all set to 0.
- Power on the Avenger96 board.
- Verify using '$ dmesg' that a new device has been detected as follows:
    New USB device found, idVendor=0483, idProduct=df11, bcdDevice= 2.00
    New USB device strings: Mfr=1, Product=2, SerialNumber=3
    Product: DFU in HS Mode @Device ID /0x500, @Revision ID /0x0000
    Manufacturer: STMicroelectronics

- Upload U-Boot SPL:
$ dfu-util -a 1 -D u-boot-spl.stm32
- Upload U-Boot proper:
$ dfu-util -a 0 -D u-boot.itb

- At this point, SPL will wait for user to press "Ctrl-C" on serial
  console. When ready to interact with U-Boot, press Ctrl-C to start
  the bootloader.

e1d7b0b9c5 ARM: stm32: Increase PHY auto-negotiation timeout to 20s on DHSOM
The Micrel PHYs on known DHSOM based boards take a while to come out
of reset, increase the auto-negotiation timeout to prevent it from
timing out in case the ethernet is used right after the board was
reset.

44beea2845 ARM: stm32: Add update_sf script to install U-Boot into SF on DHSOM
Add script to read U-Boot from SD card and write it to matching
locations in the SPI NOR, thus making the SPI NOR bootable. The
script erases the entire SPI NOR, including U-Boot environment,
to make sure the installation is clean. To retain environment
from current running U-Boot, run 'saveenv' after running the
'update_sf' script.

e8e66801bd ARM: stm32: Increase USB power-good delay on DHSOM
The USB hub on STM32MP1 DHCOM boards needs to wait a bit longer until
the USB Vbus is stable. Increase the USB power-good delay to 1 s.

This adds default-undefined STM32MP_BOARD_EXTRA_ENV variable into
stm32mp15_common.h to reduce duplication in board-specific config
files adding custom environment.

c67ca25dfc board: stmp32mp1: split board and SOC STM32MP15 configuration
Add a configuration file "stm32mp15_st_common.h" to handle the
STMicroelectronics boards configuration and rename stm32mp1.h to
"stm32mp15_common.h" to handle the generic STM32MP15x series configuration.

The configuration file "dh_stm32mp1.h" is also renamed to
"stm32mp15_dh_dhcom" for the configuration of board based on the
dhelectronics STM32MP15x SOM.

In the STMicroelectronics board configuration the default bootcmd
"bootcmd_stm32mp" is updated to only select the extlinux file found on
SD-Card on STM32MP15x EV1 for boot from NOR device.
