Subject: [PATCH] arm64: Add DTS overlays for A64

 - sun50i-a64-sid.dtso registers the Security ID node, needed for thermal
 - sun50i-a64-ths.dtso registers the thermal node, for which we already have a
driver
 - sun50i-a64-timer.dtso registers the timer node, needed as the generic timer
 glitch on A64 SoC.
