This commit implements a character driver for the general purpose ADC of the BL808, based on the hardware scanning functionality. The driver supports setting different conversion resolutions and the order of channels to be scanned via menuconfig.
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.

- This PR adds the LED Driver for Ox64 Board (User LEDs and Auto LEDs)
- Ox64 LED Driver will be used by the Rust Blinky App for Google Summer of Code
- User LED 1 is configured for GPIO 29. Other User LEDs and Auto LEDs shall be configured by the NuttX Dev.
- The code is derived from NuttX PinePhone LED Driver

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 commit modifies the existing serial driver to add support for the remaining UARTs on the BL808. It also introduces support for setting baud rate, character length, stop bits, parity, flow control and which serial port acts as the console.
This change implements a system for allowing the D0 core (which runs NuttX) to receive forwarded interrupts from the M0 core. This makes it possible for drivers that rely on interrupts to work with peripherals attached to the M0 core.
As suggested in PR:12530, changed the default names of ESP32S3WROOM chips to ESP32S3WROOM1N4,
ESP32S3WROOM2N16R8, ESP32S3WROOM2N32R8, ESP32S3MINI1N8.
Also regenerated all the defconfigs for board configurations.
Added a custom ESP32S3 module for custom flash configurations.
Declared ESP32S3_PSRAM_8M variable with prompt
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:

There is no need to use kernel build for S-mode all the time. As cpu
scratch is supported for non kernel mode build, it is possible to use
flat build for S-mode.
Add flat build support for risc-v S mode.

This provides an alternate tickless scheduling method, which uses the riscv
mtimer as a timebase, allowing the time and timeh registers to used
throughout an application.
The exiting tickless method, using Litex's timer0 has been left in place, as
it is a more performant option, but currently has the potential issue
identified in #11189.
