mpsl: Increase default config for how often hfpll is calibrated

It is a bit excessive to calibrate hfpll every 4s.
Increasing to 60s to save power in the case where LFRC
calibartion doesnt happen (when LFXO is used).

 	  This configuration means how often the calibration callback to mpsl is called.
 	  On 54L, this still needs to be called even if LFRC is not used.
