p1_p2_rdb: to set SQW/INT pin of RTC as INT line
SQW/INT pin in RTC can be used for generating square wave(by default) or as interrupt line. U-boot is registering this pin for interrupts. Configuring SQW/INT bit as interrupt line during board initialization to avoid spurious interrupts generated by square wave.
