arm64/a64: Add drivers for PIO and LEDs

This PR adds the drivers for Allwinner A64 PIO (Programmable I/O) and PinePhone LEDs (Red / Green / Blue).

The PIO Driver is based on the NuttX PIO Driver for Allwinner A10: [`arch/arm/src/a1x/a1x_pio.c`](https://github.com/apache/nuttx/blob/master/arch/arm/src/a1x/a1x_pio.c)

-   `arch/arm64/src/a64/Make.defs`: Add PIO Driver to Makefile

-   `boards/Kconfig`: Add `ARCH_HAVE_LEDS` to PinePhone

-   `boards/arm64/a64/pinephone/src/pinephone.h`: Define PinePhone LEDs

-   `boards/arm64/a64/pinephone/src/pinephone_boardinit.c`: Start Auto LEDs

-   `boards/arm64/a64/pinephone/src/pinephone_bringup.c`: Start User LEDs

-   `boards/arm64/a64/pinephone/src/Makefile`: Add LED Driver to Makefile

-   `boards/arm64/a64/pinephone/configs/nsh/defconfig`: Add `CONFIG_USERLED` to `nsh` config

-   `arch/arm64/src/a64/a64_pio.c`, `a64_pio.h`: Allwinner A64 PIO Driver

-   `arch/arm64/src/a64/hardware/a64_memorymap.h`: PIO Memory Map

-   `arch/arm64/src/a64/hardware/a64_pio.h`: PIO Definitions

-   `boards/arm64/a64/pinephone/include/board.h`: Define PinePhone LEDs

-   `boards/arm64/a64/pinephone/src/pinephone_autoleds.c`: Driver for Auto LEDs

-   `boards/arm64/a64/pinephone/src/pinephone_userleds.c`: Driver for User LEDs

-   `introduction/supported_platforms.rst`: Add Allwinner A64 as Supported Platform

-   `platforms/arm/a64/boards/pinephone/index.rst`: Add PIO and LEDs to PinePhone

* Description:
* This function is called very early in initialization to perform board-

* things as, for example, configure GPIO pins to drive the LEDs and also
* putting the LEDs in their correct initial state.
*
* NOTE: In most architectures, board_autoled_initialize() is called from
* board-specific initialization logic. But there are a few architectures
* where this initialization function is still called from common chip
* architecture logic. This interface is not, however, a common board
* interface in any event and, hence, the usage of the name
* board_autoled_initialize is deprecated.
*
* WARNING: This interface name will eventually be removed; do not use it
* in new board ports. New implementations should use the naming
* conventions for "Microprocessor-Specific Interfaces" or the "Board-
* Specific Interfaces" as described above.
*
* Input Parameters:
* None

* Name: board_userled_initialize

* Description:
* This function may called from application-specific logic during its
* to perform board-specific initialization of LED resources. This
* includes such things as, for example, configure GPIO pins to drive the
* LEDs and also putting the LEDs in their correct initial state.
*
* If CONFIG_ARCH_LEDS is defined, then NuttX will control the on-board
* LEDs. If CONFIG_ARCH_LEDS is not defined, then this interfaces may be
* available to control the LEDs directly from user board logic or
* indirectly user applications (via the common LED character driver).
*
* Most boards have only a few LEDs and in those cases all LEDs may be
* used by the NuttX LED logic exclusively and may not be available for
* use by user logic if CONFIG_ARCH_LEDS=y.
*
* NOTE: The LED number is returned.
*
* Input Parameters:
* None
*
* Returned Value:
* Number of LEDs on board
