Patrick Georgi f943901777 mc146818rtc: disable RTC before writing to nvram
In principle this isn't necessary. However there's a byte (or several)
outside the first 14 bytes that are part of the RTC, and require
locking (century/altCentury).

Since their location is mostly unknown, guard writes properly.
