as3277: Fix month-off-by-one error for RTC driver

The AS3277 RTC code seems to closely follow the corresponding Linux
driver. Unfortunately, while coreboot (and even other parts of Linux,
like mktime()) directly follows the standard IBM PC RTC time
representation (except for the BCD part), Linux' struct rtc_time decided
to use 0-based (instead of 1-based) months instead.

This patch removes the faulty month offset that was copied into our
driver so that we will generate correct timestamps again.

BRANCH=nyan
BUG=chrome-os-partner:34108
TEST=firmware_EventLog (pre-release version) gets further than before
(and then craps up on unrelated problems with suspend/resume events).
