arm64/a64: Add driver for Display Engine
This PR adds the driver for Display Engine 2.0 on Allwinner A64 SoC. The Display Engine Driver will be called by the upcoming LCD Driver for PINE64 PinePhone. `arch/arm64/src/a64/Kconfig`: Added the Kconfig option for "A64 Peripheral Selection > DE" (`CONFIG_A64_DE`), which enables the Display Engine Driver `arch/arm64/src/a64/hardware/a64_memorymap.h`: Added the Base Address for Display Engine `arch/arm64/src/a64/Make.defs`: Added the Display Engine Driver to the Makefile `boards/arm64/a64/pinephone/configs/nsh/defconfig`: Removed Scheduler Debug Info (`CONFIG_DEBUG_SCHED_INFO`) from the PinePhone Board Config, because it garbles the Console Output. `arch/arm64/src/a64/a64_de.c`, `a64_de.h`: Display Engine Driver for Allwinner A64 `platforms/arm/a64/boards/pinephone/index.rst`: Added Display Engine as supported peripheral for PinePhone
