[ Upstream commit 3180cfabf6fbf982ca6d1a6eb56334647cc1416b ]
Unbreak CPCAP driver, which has one more bit in the day counter increasing the max. range from 2014 to 2058. The original commit introducing the range limit was obviously wrong, since the driver has only been written in 2017 (3 years after 14 bits would have run out).
