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.
