4c8d244fae sched/getpid: replace syscall getpid/tid/ppid() to kernel version
NuttX kernel should not use the syscall functions, especially after
enabling CONFIG_SCHED_INSTRUMENTATION_SYSCALL, all system functions
will be traced to backend, which will impact system performance.

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

bf91047f33 libc: Fix getrandom() bug: Didn't propagate read error
* libs/libc/misc/lib_getrandom.c, in function getrandom():
  We were assigning the return value of _NX_READ() to nbytes, a
  variable of the unsigned type size_t. Note that _NX_READ() resolves
  to either read() or nx_read(), both of which return the signed type
  ssize_t to indicate either the number of bytes read successfully
  (>= 0) or an error (< 0). Then we were testing for a negative
  size_t value, a condition that can never occur. The end result is
  that if an error occured in _NX_READ(), it would never be detected
  and getrandom() would return some large positive value. This bug is
  corrected by assigning the return value of _NX_READ() to a new local
  variable, ret, of size ssize_t.
