elog: fix improper assumption for year values

The elog format stores the year of the event in bcd format.
    Semi-recently rtc_get() started returning the full year,
    e.g. 2015. However, bin2bcd takes a uint8_t as a parameter.
    Converting a full year (2015 or 0x7df) to a uint8_t results
    in passing bad values (223 or 0xdf) to bin2bcd. In other words
    the input value of bin2bcd needs to be a number between 0 and 99.
    Therefore fix that mistake.

BUG=chrome-os-partner:47388
    BRANCH=None
    TEST=Events show up with correct year in eventlog now.
