This PR adds support for the PINE64 Yuzuki Avaota-A1 SBC, based on Allwinner A527 Arm64 SoC. 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 platforms/arm64/a527/index.rst: Added Avaota-A1 to Allwinner A527 SoC platforms/arm64/a527/boards/avaota-a1/avaota-a1.jpg: Photo of Avaota-A1, taken by me platforms/arm64/a527/boards/avaota-a1/index.rst: Building and booting NuttX for Avaota-A1 Signed-off-by: Lup Yuen Lee <luppy@appkaki.com>
