Alexander Couzens f8970f53ef mainboard/lenovo: reserve century byte
The century byte is used by most RTC (default 0x32@nvram).
Even the century byte can disabled via ACPI it's more safe to reserve
it's space. Because some RTC will act with that byte anyhow.
Some OS overwrite it when syncronize the RTC.
