[nrf noup] platform: Disable default RTC30 IRQ handler

-RTC30 is generally not intended for use in L15 device and causes
 falures on nRF54L10 and nRF54L05 devices as it collides with
 CLOCK_POWER IRQ. This commit fixes these issues

NOTE: This is a short-lived noup as it will be part of the adding
nRF54L15 in upstream TF-M. See referenced jira
