Instead of using arch_segment_loaded() implement
platform_segment_loaded() so as not to tangle the notion of
arch and the chipset. Lastly, add a TODO to allow filtering
of the L1D to L2 flush depending on the region loaded.

Instead of using platform_prog_run() for flushing programs
from L1D to L2 for code coherency purposes use arch_segment_loaded()
instead as that it's primary purpose. The arch_segment_loaded()
is called within the infrastructure at the appropriate places when
loading programs. Therefore use that to perform the L1D flush
instead of when something is just about to run.

The flush L1D to L2 operation was only being used when loading
romstage from bootblock. However, when the FSP-M component is
loaded no code coherency actions are taken. I suspect this is
because the FSP-M component is larger than the 24KiB L1D and
the entry point is early in the image. Thus, when loading
the FSP-M component the earlier part of the image is flushed
out to L2 in the process of loading the latter part of the
component. Also, once verstage is introduced the same
code coherency actions need to be taken as well. Therefore,
position the apollolake code to handle all these cases.
