Caching is a very architecture-specific thing, but most architectures
have a cache in general. Therefore it can be useful to have a generic
architecture-independent API to perform simple cache management tasks
from common code.
We have already standardized on the dcache_clean/invalidate naming
scheme that originally comes from ARM in libpayload, so let's just do
the same for coreboot. Unlike libpayload, there are other things than
just DMA coherency we may want to achieve with those functions, so
actually implement them for real even on architectures with
cache-snooping DMA like x86. (In the future, we may find applications
like this in libpayload as well and should probably rethink the API
there... maybe move the current functionality to a separate
dma_map/unmap API instead. But that's beyond scope of this patch.)

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).
