Log Message:
port-evbarm/53308: evbarm-earmv7hf performance regression under qemu

Revert gtmr.c r1.27 and apply a workaround for Allwinner A64 SoCs based
on analysis of the issue from LKML: https://lkml.org/lkml/2018/5/10/774

Since this bug is specific to the Allwinner A64 SoC, only apply the
workaround when the root ("/") node of the device tree is compatible
with "allwinner,sun50i-a64".
