rtc: pcf85363: fix wrong mask/val parameters in regmap_update_bits call

Browse source 
[ Upstream commit 2be36c09b6 ]

The current implementation passes PIN_IO_INTA_OUT (2) as a mask and
PIN_IO_INTAPM (GENMASK(1, 0)) as a value.
Swap the variables to assign mask and value the right way.

This error was first introduced with the alarm support. For better or
worse it worked as expected because 0x02 was applied as a mask to 0x03,
resulting 0x02 anyway. This will of course not work for any other value.
