arm64: dts: qcom: sc8280xp-pmics: add explicit rtc interrupt parent

Unless explicitly specified the interrupt-parent property is inherited
from the parent node on Linux even though this may not be in full
compliance with the devicetree specification.

Following commit 2d5cab9232ba ("arm64: dts: qcom: sc8280xp-pmics:
Specify interrupt parent explicitly"), add an explicit interrupt parent
also for the PMIC RTC node for the benefit of other operating systems
which may be confused by this omission.

Note that any such OS must still implement a fallback to the root
interrupt domain as most devicetrees are written under the assumption
that the interrupt parent is inherited.
