arm64: dts: rockchip: Drop RTC clock-frequency on rk3588-rock-5b

The hym8563 RTC driver doesn't handle the 'clock-frequency' property,
which is also indicated by the following dtbs_check warning:

  rk3588-rock-5b.dtb: rtc@51: Unevaluated properties are not allowed ('clock-frequency' was unexpected)
  From schema: Documentation/devicetree/bindings/rtc/haoyu,hym8563.yaml

Drop the unsupported property.
