Michal Simek d7b5cc89d3 microblaze: Do not place u-boot to reserved memory location 
Microblaze can also have reserved space in DT which u-boot has to avoid to
placing self to that location. The same change was done in Zynqmp by commit
ce39ee28ec ("zynqmp: Do not place u-boot to reserved memory location").

This feature was tested with this memory description on kc705:

	memory {
		device_type = "memory";
		reg = <0x80000000 0x40000000>;
	};

	reserved-memory {
		#address-cells = <1>;
		#size-cells = <1>;
		ranges;

		alloc@b00000000 {
			reg = <0xb0000000 0x10000000>;
			no-map;
		};

		alloc@a8000000 {
			reg = <0xa8000000 0x00010000>;
			no-map;
		};
	};

And in U-Boot log you can check u-boot relocation address and reserved
locations.
