Yanfeng Liu a4b22fe999 risc-v/k230: initial Asymmetric Multi-Processing support
K230 chip has two T-Head C908 RiscV cores, previously we run NuttX
on either little or big cores. This patch runs NuttX on both cores
with OpenAMP support via the RPTUN driver.

New additions:

- in arch/risc-v/src/k230
  - k230_rptun.c              K230 RPTUN driver
  - k230_rptun.h              K230 RPTUN driver header file

- in baords/risc-v/k230/canmv230
  - configs/master            Build config for master node
  - configs/remote            Build config for remote node
  - scripts/ld-rptun.script   Build script for RPTUN

Major changes:

- arch/risc-v/Kconfig         Select NUTTSBI_LATE_INIT upon NUTTSBI
- in arch/risc-v/include
  - k230/irq.h                Add UART3 IRQ defs
- in arch/risc-v/src/k230
  - Kconfig                   Add RPTUN related config items
  - Make.defs                 Add k230-rptun.c to sources
  - hardware/k230_memorymap.h Add K230 device and CSR defs
  - k230_hart.c               Add hart ctrl for RPTUN
  - k230_hart.h               Add hart ctrl for RPTUN
  - k230_mm_init.c            Add Svpmbt to support RPTUN
  - k230_start.c              Revised to support RPMsg UART
- in boards/risc-v/k230/canmv230
  - scripts/Make.defs         Add RPTUN script selection
  - src/canmv_init.c          Add RPTUN and RPMsg_UART initialization
- in Documentation/platforms/risc-v/k230/boards/canmv230
  - index.rst                 Add AMP usage information.
