nyan*: Add an empty elog functions for the !CONFIG_ELOG case 

Provide elog stub functions so eventlog support can be omitted
without littering code with "#if CONFIG_ELOG".

This makes it so coreboot can be built without eventlog support for
these platforms for debugging purposes.

BUG=none
BRANCH=none
TEST=compiled for Nyan and Rambi with CONFIG_ELOG unset
