Instead of assuming SPI backing use a region_device to abstract away the underlying storage mechanism.

This option will have ELOG store a copy of the flash event log
|
|
in a CBMEM region and export that address in SMBIOS to the OS.
|
|
This is useful if the ELOG location is not in memory mapped flash,
|
|
but it means that events added at runtime via the SMI handler
|
|
will not be reflected in the CBMEM copy of the log.
