b895207489 arm64/a64: Add driver for MIPI DSI
This PR adds the driver for Allwinner A64's MIPI Display Serial Interface (DSI) and MIPI Display Physical Layer (D-PHY).

This driver will be used by the upcoming Display Driver for PINE64 PinePhone.

- `include/nuttx/crc16.h`: Added 16-bit CRC-CCITT

- `libs/libc/misc/Make.defs`: Added 16-bit CRC-CCITT to Makefile

- `arch/arm64/src/a64/Kconfig`: Added the Kconfig option for "A64 Peripheral Selection > MIPI DSI" (`CONFIG_A64_MIPI_DSI`), which enables the MIPI DSI Driver

- `arch/arm64/src/a64/hardware/a64_memorymap.h`: Added the Base Address for MIPI DSI

- `arch/arm64/src/a64/Make.defs`: Added the MIPI DSI Driver to the Makefile

- `libs/libc/misc/lib_crc16ccitt.c`: Compute 16-bit CRC-CCITT

- `arch/arm64/src/a64/mipi_dsi.c`, `mipi_dsi.h`: Compose MIPI DSI Packets (Long, Short, Short with Parameter)

- `arch/arm64/src/a64/a64_mipi_dsi.c`, `a64_mipi_dsi.h`: MIPI DSI Driver for Allwinner A64

- `arch/arm64/src/a64/a64_mipi_dphy.c`, `a64_mipi_dphy.h`: MIPI D-PHY Driver for Allwinner A64

- `platforms/arm/a64/boards/pinephone/index.rst`: Added MIPI DSI as supported peripheral for PinePhone

40179da030 Squashed commit of the following:
libs/libc/misc/Make.defs:  For platforms whose CPP tool does not support a variable number arguments to pre-processor macros, we may still need to build the debug functions even when CONFIG_DEBUG_FEATURES is not selected.  For example, __alert() may be needed is CONFIG_ARCH_STACKDUMP is set.

    configs/makerlisp:  Add an sdboot configuration that will load .hex files from the SD card.

cf99fb40c9 This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now.
Squashed commit of the following:

    libs/libxx:  Fix some confusing in naming.  If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
    libs/:  Fix paths in moved library directories.
    libs:  Brute force move of libc, libnx, and libxx to libs.  Cannot yet build it in that configuration.
