board/km: add support for seli8 design based on nxp ls102x

The SELI8 design is a new tdm service unit card for Hitachi-Powergrids
XMC and FOX product lines.

It is based on NXP LS1021 SoC and it provides following interfaces:
 - IFC interface for NOR, NAND and external FPGA's
 - 1 x RGMII ETH for debug purposes
 - 2 x SGMII ETH for management communication via back-plane
 - 1 x uQE HDLC for management communication via back-plane
 - 1 x I2C for peripheral devices
 - 1 x SPI for peripheral devices
 - 1 x UART for debug logging

It is foreseen that the design will be later re-used for another XMC and
FOX service cards with similar SoC requirements.
