[PATCH v3] xen/arm: Don't use copy_from_paddr for DTB relocation

Currently the early stage of the Arm boot maps the DTB using early_fdt_map() using PAGE_HYPERVISOR_RO which is cacheable read-only memory, later during DTB relocation the function copy_from_paddr() is used to map pages in the same range on the fixmap but using PAGE_HYPERVISOR_WC which is non-cachea
