Kconfig: lay groundwork for not assuming SPI flash boot device
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.
