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.

e0f21e1cbc microblaze: Fix C99/gnu99 compatiblity for inline functions
'extern inline' is not portable across various C standards. To ensure
compatiblity with various standards/compilers change the functions to
static inline. This is a portable construct and serves as a comparable
definition to 'extern inline' from the gnu90 standard.

Additionally remove the function prototypes as they are not required due
to the functions being declared static and functions are correctly
ordered based on dependence.

819833af39 Move architecture-specific includes to arch/$ARCH/include/asm
This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
