drivers/elog: remove elog Kconfig variables
Now that FMAP is a first class citizen in coreboot
there's no reason to have alternate locations for ELOG.
If one wants eventlog support they need to specify the
ELOG entry in the FMAP. The one side effect is that
the code was previously limiting the size to 4KiB
because the default ELOG_AREA_SIZE was 4KiB. However,
that's no longer the case as the FMAP region size is
honored.
