net: Move env_get_ip() out of the header file

This function requires access to env.h but it is a lot to include just
for the env_get() function. It eventually pulls in linux/byteorder which
causes a conflict with exfat which has its own byteorder functions.

Move the function to a C file instead.

Add includes to some other files to keep the build working.

- Add patches for other files exposed by this change

Cover-letter:
Deal with exfat versus byteorder
Since exfat has its own byteorder functions we need to be careful about
including the normal U-Boot byteorder headers in code included by exfat.

One chain for include/linux/byteorder/little_endian.h is like this:

In file included from arch/sandbox/include/asm/byteorder.h:19,
                 from arch/sandbox/include/asm/byteorder.h:19,
                 from include/compiler.h:132,
                 from include/env.h:12,
                 from include/command.h:13,
                 from include/net-common.h:7,
                 from include/net.h:6,
                 from include/efi.h:23,
                 from include/blk.h:12,
                 from include/part.h:9,
                 from include/fs_internal.h:11,
                 from fs/exfat/io.c:52:

This series tidies things up so that efi.h can include net.h as
required.
