Subject: [U-Boot] [PATCH][v0]p1_p2_rdb: to set SQW/INT pin of RTC as INT
line

p1_p2_rdb : 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.
