relocate_to_adr() currently relocates the PBL code to another address,
but doesn't move the piggy data (compressed barebox image). This patch
adds relocate_to_adr_full() which moves the full image including the
piggy data. This is needed for upcoming Rockchip RK3568 support. Here
we are started at address 0x0, but must move away from that address as
this is where the ATF/OP-Tee binaries are expected to be loaded.

We have several places in the code which which prepares just modified code
for execution. This is done differently in all the places, so add a common
function to be used by all.
Most places called arm_early_mmu_cache_flush(). This function includes
invalidating the instruction cache, so doing it again is unnecessary.
Sometimes we had arm_early_mmu_cache_flush() inside #ifdef CONFIG_MMU.
The ifdef seems unnecessary since we do not have it consistently, so
remove the ifdef.
Some early i.MX xload code had icache_invalidate() but forgot to flush
the caches. Replace the instruction cache invalidation with
sync_caches_for_execution().

This adds aarch64 support for relocating binaries linked with -pie.
Support is integrated into the already exisiting
relocate_to_current_adr() function which is now used for both arm32
and aarch64.
