p1_p2_rdb: to set SQW/INT pin of RTC as INT line

Browse Source 
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.
