[Felix Brack]

This patch adds support for the PDU001 board.

Signed-off-by: Felix Brack

Changes in v4:
- move remaining U-Boot specific parts from DTS to DTSI file

Changes in v3:
- revert to deprecated SPDX license identifier GPL-2.0+
- maintain alphabetical order in Kconfig files
- move U-Boot specific parts from DTS to new DTSI file to simplify
  longterm maintenance

Changes in v2:
- use DT to configure the board
- use new single-register pin controller
- use new TPS65910 PMIC driver
- eliminate the need of CONFIG_DM_I2C_COMPAT, i.e. use DM for i2c
- clarify the function of the 'Run LED'
- fix ordering of include files
- replace deprecated SPDX license identifiers
