Describe the QSPI flash SFDP as an NVMEM provider with the
microchip,sst26vf-sfdp-eui layout, which exposes the factory-programmed
EUI-48 as a "mac-address" cell, and point macb0 at it through
nvmem-cells. This yields a stable MAC address on boards where U-Boot does
not program one, instead of falling back to a random address.
