WIP: Add configurable ramstage support for minimal PCI scanning
This CL has changes that allow us to enable a configurable ramstage, and one change that allows us to minimize PCI scanning.
We add two new variables to src/Kconfig: CONFIGURABLE_RAMSTAGE is the overall variable controlling other options for minimizing the ramstage.
MINIMAL_PCI_SCANNING is how we indicate we wish to enable minimal PCI scanning.
To indicate which devices we must scan, we add a new always_scan struct member to the pci driver. Drivers which must always be scanned can set this to 1.
It is not clear that this approach is close to correct, so comments are welcome.
