arm64: sunxi: Build the sun4i timer driver

While the ARM architectural timer is generatlly the best timer to use,
a non-c3stop timer is needed for cpuidle.

Build the "sun4i" timer driver so it can be used for this purpose.
It is present on all 64-bit sunxi SoCs.

          This enables support for Allwinner sunxi based SoCs like the A64.
