ppc: qemu: Delete the temporary FDT virtual-physical mapping after U-Boot is relocated
After U-Boot is relocated to RAM already, the previous temporary FDT
virtual-physical mapping that was used in the pre-relocation phase
is no longer needed. Let's delete the mapping.
get_fdt_virt() might be used before and after relocation, update it
to return different virtual address of FDT.
