Uwe Kleine-König fbbf53f702 rtc: pcf8523: refuse to write dates later than 2099 ...

When the chip increments the YEAR register and it already holds
bin2bcd(99) it reads as 0 afterwards. With this behaviour the last valid
day (without trickery) that has a representation is 2099-12-31 23:59:59.
So refuse to write later dates.
