astbmc: asynchronous preloading of resources
Implement start_preload_resource and resource_loaded platform functions
for astbmc machines (palmetto, habanero, firestone).
This means we start loading kernel and initramfs from flash much earlier
in boot, doing things like PCI init concurrently so that by the time
we go to boot the payload, it's already loaded.
Implementation is a simple queue with a job running on another CPU doing
the libflash calls.
