rtc: pcf85363: fix wrong mask/val parameters in regmap_update_bits call
[ Upstream commit 2be36c09b6b07306be33519e1aa70d2e2a2161bb ] 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.
