commit 6c883472e1c11cb05561b6dd0c28bb037c2bf2de upstream.
When RTC is used in 24H mode (and it is by this driver) the maximum hour value is 24 in BCD. This occupies bits [5:0] - which means correct mask for HOUR register is 0x3f not 0x1f. Fix the mask
Fixes: 32a4a4ebf768 ("rtc: bd70528: Initial support for ROHM bd70528 RTC")
