soc/amd/cezanne: Add ASYNC_FILE_LOADING

This gives us a knob that can be controlled via a .config to
enable/disable file preloading. I left the option disabled because
there is currently a race condition that can cause data corruption when
using the SPI DMA controller. The fix will actually introduce a
boot time regression because the preloads are happening at the same time
as the elog init. I want to keep preloading disabled for now until
I get all the sequencing worked out.

BUG=b:179699789
TEST=Boot guybrush and verify no preloading happens.
