arm64: dts: qcom: sc8280xp-arcata: Switch to uefi rtc offset

Browse source

Align with the reference implementation from the ThinkPad X13s:

Switch to using the Qualcomm specific UEFI variable that is used by the
UEFI firmware (and Windows) to store the RTC offset.

Use the new 'qcom,uefi-rtc-info' property to indicate that the offset is
stored in a UEFI variable so that the OS can determine whether to wait
for it to become available.
