arm64: zynqmp: Update rtc calibration value
As per the design specification
"The 16-bit Seconds Calibration Value represents the number of
Oscillator Ticks that are required to measure the largest time
period that is less than or equal to 1 second.
For an oscillator that is 32.768 KHz, this value will be 0x7FFF."
