[PATCH 17/24] arm64: dts: qcom: glymur-crd: Avoid RTC probe failure

From: Kamal Wadhwa <kamal.wadhwa@oss.qualcomm.com>

On Glymur boards, the RTC alarm interrupts are routed to SOCCP
subsystems and are not available to APPS. This can cause the
RTC probe failure as the RTC IRQ registration will fail in
probe.

Fix this issue by adding `no-alarm` property in the RTC DT
node. This will skip the RTC alarm irq registration and
the RTC probe will return success.
