This commit implements the RMT peripheral for all the supported
Espressif's RISC-V devices. It also implements the support for the
WS2812 addressable RGB LED using the RMT peripheral.
WS2812 data is encoded into RMT items according to the RMT clock
source. This commit makes it by using the actual clock source in
spite of a pre-defind value.
This commit adds support to autoleds and userleds for
raspberrypi-pico board. It uses the board LED connected
to GPIO 25.

- remove read-write logic - this should be handled by radio protocol implementation
- remove EVENTS and TASKS bit definitions - we can just use a signle definition
- add more radio ops
- fix frequency configuration
- fix printf warnings
- fix radio reset
Simply the config, later we can directly use macro SIM_RPMSG_MASTER
to controll all the rpmsg transport init.

since clock_t may map to either 32-bit or 64-bit integer type,
UINT_MAX may not be the maximum value of clock_t.

Inclusion of mach/mach_time.h by libcxx/src/chrono.cpp breaks
the build on latest MACOS dues to https://forums.developer.apple.com/forums/thread/746737
The interface from mach/mach_time.h is not referenced in chrono.cpp
so it is safe to remove it

I noticed when executing pwm STOP command in
multichannel mode, the channel still outputting.
This commit fixes this issue.

This patch revises `k230_hart.[ch]` by:
- revising big core boot/stop control.
- making k230_hart_is_big() available in S-mode.
- adding more comments.
This patch also revises the `ld-kernel.script` so that to match the
latest MMU pgtable design.

There have been errors like below on macOS for sim:libcxxtest
```
Error: /Applications/Xcode.../include/mach/vm_page_size.h:59:44:
error: expected ';' after top level declarator
```
This patch tries to disable that check on macOS.

This adds initial document for using TMPFS based on my short experience,
hoping to save people's time on guessing how to use.

I used
cd nuttx
cmake -B build -DBOARD_CONFIG=stm32f401rc-rs485:nsh -GNinja
to config
and when following the instruction in this official websites I found the
command to use cmake to build the target is wrong.
which is "cmake --build build -t menuconfig" also wrong the output dir
"build/nuttx".
and by the way, In my practice I find the bin file and elf file is not
in build/nuttx but in build/. So I changed these. But I'm not 100% sure
that my fix is right as I'm a beginner, but what I fix works fine in my
computer. This is my first PR to the public doc. My fix maybe totally
wrong as I am not get into the nuttx, just following the instruction and
encountered some mistakes.
thx for reviewing

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.
