drivers/elog: put back 4KiB limit
The removal of ELOG_FLASH_BASE and ELOG_FLASH_SIZE resulted
in the FMAP region for the eventlog to be honored. However,
certain systems seem to have a large eventlog region that
wasn't being used in practice. Because of the malloc() in the
eventlog init sequence a large allocation was now being requested
that can exhaust the heap. Put back the 4KiB capacity until
the resource usage is fixed.
