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
