- This PR adds the LED Driver for QEMU RISC-V 32-bit and 64-bit (User LEDs and Auto LEDs)
- QEMU RISC-V LED Driver will be used by the Rust Blinky App for Google Summer of Code
- Blinking the LED is probably the most common Embedded Demo, and now it's supported by QEMU RISC-V
- We added NuttX Configs `rv-virt:leds` and `rv-virt:leds64` to support User LEDs for 32-bit and 64-bit RISC-V
- Turning on/off a Simulated User LED will print a log message: "LED 1 set to 1"
- The code is derived from NuttX PinePhone LED Driver
NuttX generates the app main name from Kconfig symbol
xxxx_PROGNAME. The documentation was defining manually
the entry point as custom_hello(int char, char *argv[])
and pointing CONFIG_INIT_ENTRYPOINT="custom_hello".
The right thing to do is creating the application entry
point as "int main(int char, char *argv[])" and the build
system will add "_main" to the PROGNAME.

This adds out-of-tree usage guide of CMake for FLAT, PROTECTED and KERNEL
configs so that more kernel developers can enjoy cmake for their daily
work.

This does the following:
1. Fetches mkimage_imx8 (same used with imx9) source code
2. Fetches the ELE / AHAB binary
3. Extracts the ELE / AHAB binary
4. Compiles the mkimage with hostcc
5. Utilizes the mkimage tool to create a bootable SD image,
combining the ELE / AHAB image with the NuttX bootloader
6. dd is used to prepend empty space in place of BL31
7. Outputs sdimage.img which is a bootable binary
8. Removes all binaries, sources code images that have been
downloaded

The Simple Boot feature for Espressif chips is a method of booting
that doesn't depend on a 2nd stage bootloader. Its not the
intention to replace a 2nd stage bootloader such as MCUboot and
ESP-IDF bootloader, but to have a minimal and straight-forward way
of booting, and also simplify the building.
This commit also removes deprecated code and makes this bootloader
configuration as default for esp32 targets and removes the need
for running 'make bootloader' command for it.

Squashed:
Initial settings for MCPWM Capture on board level
Created lower half files - compilation ok
Using capture debug features. Simple example on fops works
Successful duty and freq calculation
Documentation update
Fixed and added interupt capabilities for all 3 capture channels
Cleaned defconfig
Renamed macros, added S3 options and moved arch source to common dir
Added support for ESP32S3
Added capture example to defconfig and renamed
This PR adds support for Milk-V Duo S 64-bit RISC-V SBC, based on SOPHGO SG2000 SoC (T-Head C906 Core). Most of the code is derived from NuttX for Ox64 BL808. The source files are explained in the articles here: https://github.com/lupyuen/nuttx-sg2000
Modified Files:
`boards/Kconfig`: Added Milk-V Duo S board
`arch/risc-v/src/sg2000/sg2000_timerisr.c`: Fixed MTIMER_FREQ for sleep() to work correctly
New Files in boards/risc-v/sg2000/milkv_duos:
`src/sg2000_appinit.c`: Startup Code
`include/board.h`: Milk-V Duo S Definitions
`include/board_memorymap.h`: Memory Map
`src/etc/init.d/rc.sysinit`, `rcS`: Startup Script
`src/.gitignore`: Ignore the tmp filesystem
`scripts/ld.script`: Linker Script
`scripts/Make.defs`: Milk-V Duo S Makefile
`src/Makefile`: Milk-V Duo S Makefile
`Kconfig`: Milk-V Duo S Config
`configs/nsh/defconfig`: Build Config for `milkv_duos:nsh`
Updated Documentation:
`platforms/risc-v/sg2000/index.rst`: New page for SOPHGO SG2000 SoC
`platforms/risc-v/sg2000/boards/milkv_duos/index.rst`: Building and booting NuttX for Milk-V Duo S
As kernel mode is not necessary for S mode build, update related
information for the rv-virt board.
