[PATCH 0/5] riscv: dts: spacemit: k3-com260: Describe SD card, SPI NOR and MAC

The SD card slot and the SPI NOR flash of the K3 CoM260 module, and the
MAC address stored in its EEPROM, are part of the module, but they are
either described only in the IFX carrier device tree or not described
at all.

Fix the SD card power description, move the SD card slot into the
shared CoM260 device tree and describe the SPI NOR flash there. Enable
the AT24 EEPROM driver and the ONIE TLV layout in the RISC-V defconfig,
then let the module's Ethernet controller take its MAC address from the
module EEPROM. Every carrier using the module inherits these
descriptions.
