rtc: msm6242: Fix reading of 10-hour digit
commit e34494c8df0cd96fc432efae121db3212c46ae48 upstream.
The driver was reading the wrong register as the 10-hour digit due to
a misplaced ')'. It was in fact reading the 1-second digit register due
to this bug.
Also remove the use of a magic number for the hour mask and use the define
for it which was already present.
Fixes: 4f9b9bba1dd1 ("rtc: Add an RTC driver for the Oki MSM6242")
