Lup Yuen Lee 9d80d6bb4f arch/arm64/a527: Add support for Allwinner A527 SoC 
This PR adds support for the Allwinner A527 Arm64 SoC.
This will be used by the upcoming port of NuttX for
PINE64 Yuzuki Avaota-A1 SBC.

Most of the code was derived from NuttX for
QEMU Arm64 Kernel Build qemu-armv8a:knsh.
The modified code is explained here:
https://lupyuen.github.io/articles/avaota#appendix-port-nuttx-to-avaota-a1

Modified Files in arch/arm64:

Kconfig: Added ARCH_CHIP_SUNXI for Allwinner 64-bit SoCs.
Added ARCH_CHIP_SUNXI_A527 for A527 SoC.
