At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

Add saveenv support for STM32MP1

This series adds saveenv support for STM32MP1 on several boot
devices. STM32MP1 is able to boot on eMMC, sdcard and NOR
(NAND support is not fully supported).

On eMMC and sdcard, environment is saved in EXT4 partition
On NOR, environment is saved in a dedicated partition
On NAND, environment is saved in a UBI volume.

This series:
  - enables NAND and NOR support on ev1 board
  - enables ENV_IS_IN_SPI_FLASH, ENV_IS_IN_UBI, ENV_IS_IN_EXT4
    flags
  - fixes get_mtdparts()
  - allows to override interface, device and partition for ext4
    environment
  - updates rule to set ENV_IS_NOWHERE value
  - introduce ENV_IS_IN_DEVICE

  to check cable detection.
- the DWC2 driver to support a new dt property
