rtc: pcf2127: add support for PCF2131 interrupts on output INT_A
The PCF2127 and PCF2129 have one output interrupt pin. The PCF2131 has
two, named INT_A and INT_B. The hardware support that any interrupt
source can be routed to either one or both of them.
Force all interrupt sources to go to the INT A pin.
Support to route any interrupt source to INT A/B pins is not supported
by this driver at the moment.
