microblaze: Use LOAD_OFFSET macro to get correct LMA for all sections
Currently, vmlinux has LMA==VMA for all sections, which is wrong for MMU
kernels. Previous patches in this series defined the LOAD_OFFSET constant,
now we make use of it in our link script.
Other minor changes in this patch:
* brace/indenting cleanup of some sections
* put __fdt_* symbols in their own section, and apply LOAD_OFFSET fixup
