google/gru: Shrink RW_ELOG region to 4KB

Since there's currently a limitation in coreboot's code that prevents
    more than 4KB to be used by the eventlog anyway, this patch shrinks the
    available RW_ELOG area in the FMAP for Gru down to 4KB. This may prove
    prudent later if we ever resolve that limitation, so that tools can rely
    on the area in the FMAP being the same as the area actually used by the
    read-only firmware code on these boards.

BRANCH=gru
    BUG=chrome-os-partner:55593
    TEST=Booted Kevin, confirmed that eventlog got written normally. Ran a
    reboot loop to exhaust eventlog space, confirmed that the shrink code
    kicks in as expected before reaching 4KB.
