arm64: versal-net: 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 32.768kHz, this value will be 0x7FFF."
