Yanfeng Liu 4456b2db29 risc-v/k230: add IPI support to speed up RPTUN/RPMSG
This patch adds inter-processor interrupt support using K230 mailbox
device to improve the RPMsg efficiency. The polling logic has been
dropped.

Major changes:

- in arch/risc-v/include/k230:
  - irq.h          add IRQ for IPI devices
- in arch/risc-v/src/k230:
  - Kconfig        add IPI related config, increase polling delay
  - Make.defs      add k230_ipi.c to CHIP_SRCS
  - k230_hart.c    fix typo, add notes of zero MISA reading w/ NUTTSBI
  - k230_irq.c     use K230_PLIC_IRQS as ext IRQ limit to support IPI
  - k230_rptun.c   use IPI instead of polling
- in boards/risc-v/k230/canmv230/configs
  - master         enable IPI support
  - remote         enable IPI, TMPFS, RPMSGFS etc

New additions:

- in arch/risc-v/src/k230:
  - k230_ipi.h     add K230 IPI related defintions
  - k230_ipi.c     add K230 IPI driver
