[PATCH] arm64: dts: imx8mp-debix-model-a: Remove invalid rtc property

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

Per haoyu,hym8563.yaml, 'clock-frequency' is not a valid property.

Remove it to fix the following schema warning:

imx8mp-debix-model-a.dtb: rtc at 51: Unevaluated properties are not allowed ('clock-frequency' was unexpected)
