Enable peripheral support for the NPCM845 evaluation board by wiring up the SoC controller nodes to the board design. Add board aliases, GPIO-backed MDIO buses for the external PHYs, a reserved-memory region for TIP firmware, and flash partitions for the FIU boot flash. Enable the Ethernet MACs, MMC controller, FIU controllers, USB device controllers, ADC, RNG, PWM/FAN controller, I2C buses, and PECI interface with the board-specific pinctrl and PHY connections they require.
