Subject: arm64: dts: allwinner: a64: Enable A64 timer workaround
Origin: https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/commit?id=55ec26d6a4241363fa94f15377ebd8f1116fbfd7

As instability in the architectural timer has been observed on multiple
devices using this SoC, inluding the Pine64 and the Orange Pi Win,
enable the workaround in the SoC's device tree.
