I applied this patch on top of the:
[PATCH] mtd: parsers: ofpart: limit parsing of deprecated DT syntax

I succesfully used NVMEM cell defined in bootloader mtd partition for
reading device MAC address.

partitions {
	compatible = "fixed-partitions";
	#address-cells = <1>;
	#size-cells = <1>;

	partition@0 {
		compatible = "nvmem-partitions";
		label = "bootloader";
		reg = <0x0 0x100000>;
		#address-cells = <1>;
		#size-cells = <1>;
		ranges = <0 0x0 0x100000>;

		base_mac_addr: mac@106a0 {
			reg = <0x106a0 0x6>;
		};
	};
}
