Offset into the flash chip for the ELOG block.
This should be allocated in the FMAP.

This should be a multiple of flash block size.
Default is 4K.

When the Event Log size is larger than this it will be shrunk
to ELOG_SHRINK_SIZE. Must be greater than ELOG_AREA_SIZE, and
ELOG_AREA_SIZE - ELOG_FULL_THRESHOLD must be greater than the
maximum event size of 128.
Default is 75% of the log, or 3K.
config ELOG_SHRINK_SIZE
hex "Resulting size when the event log is shrunk"
default 0x400
help
When the Event Log is shrunk it will go to this size.
ELOG_AREA_SIZE - ELOG_SHRINK_SIZE must be less than
CONFIG_ELOG_FULL_THRESHOLD.
Default is 1K.
