arm64: Align cache maintenance code with libpayload and ARM32
coreboot and libpayload currently use completely different code to
perform a full cache flush on ARM64, with even different function names.
The libpayload code is closely inspired by the ARM32 version, so for the
sake of overall consistency let's sync coreboot to that. Also align a
few other cache management details to work the same way as the
corresponding ARM32 parts (such as only flushing but not invalidating
the data cache after loading a new stage, which may have a small
performance benefit).
