ELOG: Fix reporting of developer/recovery modes 

Recent changes in EC/Vboot/U-boot have completely broken
the logging of developer and recovery modes.

Recovery mode may not be in VBNV, so if that is zero and
yet we are in recovery mode then assume it is there because
the button/key was pressed.

Since there may not be any actual developer mode switch
we look if option rom is loaded and the system is not
in recovery mode and consider that as developer mode.
