Asynchronously preload CAPP microcode
Instead of synchronously waiting for CAPP microcode during PCI probe,
start preload of CAPP microcode early in boot so that it's present
when we need it during PCI probing.
On some platforms (astbmc), flash access is serialized, and prior to
this patch, the async preload of BOOTKERNEL would have to finish before
loading CAPP ucode would start, needlessly slowing boot.
