Almost all boards and chipsets within the codebase assume or
use SPI flash as the boot device. Therefore, provide an option
for the boards/chipsets which don't currently support SPI flash
as the boot device. The default is to assume SPI flash is the
boot device unless otherwise instructed. This falls in line
with the current assumptions, but it also allows one to
differentiate a platform desiring SPI flash support while it not
being the actual boot device.
One thing to note is that while google/daisy does boot with SPI
flash part no SPI API interfaces were ever implemented. Therefore,
mark that board as not having a SPI boot device.

Since commit 3bfd7cc (drivers/pc80: Rework normal / fallback selector
code) the reboot counter stored in `reboot_bits` isn't reset on a reboot
with `boot_option = 1` any more. Hence, with SKIP_MAX_REBOOT_CNT_CLEAR
enabled, later stages (e.g. payload, OS) have to clear the counter too,
when they want to switch to normal boot. So change the bits to (h)ex
instead of (r)eserved.
To clarify their meaning, rename `reboot_bits` to `reboot_counter`. Also
remove all occurences of the obsolete `last_boot` bit that have sneaked
in again since 24391321 (mainboard: Remove last_boot NVRAM option).

A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.
All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.
The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.
