ARM: dts: armada-385-linksys: Disable internal RTC
The internal RTC does not work correctly on these Linksys boards based on Marvell SoCs. For me it only shows Wed Dec 31 23:59:59 1969 and for others it is off by 3 minutes in 10 minutes running, this was reported by multiple users. On the Linksys Mamba device the device tree comment says that no crystal is connected to the internal RTC, this is probably also true for the other devices.
