Lee Lup Yuen b31054b1e3 arch/arm64: Add support for PINE64 PinePhone
This PR adds support for PINE64 PinePhone and the Allwinner A64 SoC (based on Arm Cortex-A53).

With this PR, PinePhone boots successfully to nsh (via microSD Card) and runs console apps.

* Name: board_app_initialize
*
* Description:
* Perform application specific initialization. This function is never
* called directly from application code, but only indirectly via the
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
*
* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initialization logic and the
* matching application logic. The value could be such things as a
* mode enumeration value, a set of DIP switch switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.
