Arnaud Ebalard ecbd0b75d8 drivers/rtc/rtc-isl12057.c: fix masking of register values 
commit 5945b28803 upstream.

When Intersil ISL12057 support was added by commit 70e123373c ("rtc: Add
support for Intersil ISL12057 I2C RTC chip"), two masks for time registers
values imported from the device were either wrong or omitted, leading to
additional bits from those registers to impact read values:

 - mask for hour register value when reading it in AM/PM mode. As
   AM/PM mode is not the usual mode used by the driver, this error
   would only have an impact on an externally configured RTC hour
   later read by the driver.
 - mask for month value. The lack of masking would provide an
   erroneous value if century bit is set.

This patch fixes those two masks.

Fixes: 70e123373c ("rtc: Add support for Intersil ISL12057 I2C RTC chip")
