BREAKING: In an effort to simplify NuttX initialization, NSH_ARCHINIT is
removed. board_app_initialize is also removed. BOARD_LATE_INITIALIZE now
performs all board initialization logic, and is by default enabled. All
references to these symbols are removed. BOARDIOC_INIT remains, but will
result in -ENOTTY when called. It is to be removed in a later commit.
Quick fix: Boards relying on NSH_ARCHINIT should now enable
CONFIG_BOARD_LATE_INITIALIZE instead. If the application needs
fine-grained control over board initialization from userspace, the logic
performed by BOARDIOC_INIT may be copied to the board_finalinitialize
function and used instead via BOARDIOC_FINALINIT. All
board_app_initialize logic provided by NuttX is now moved to
board_late_initialize, and the same should be done for out-of-tree
boards.

This commit updates the common-source integration for Xtensa-based
Espressif devices (ESP32, ESP32-S2, and ESP32-S3). This is part of a larger
common-source update split by architecture for better maintainability.
Major components updated:
- IRQ allocator refactoring with intr_alloc integration
- Common-source drivers (GPIO, RMT, I2C, SPI, UART, etc.)
- Espressif components upgrade to release/master.b-test
- Peripheral drivers (ADC, PWM, LEDC, MCPWM, PCNT, Temperature Sensor, etc.)
- Wireless adapters (Wi-Fi and BLE)
- esp_timer migration to the common-source path for Xtensa devices
- Common-source power management implementation (auto-sleep and wakeup paths)
- Board defconfigs for all Xtensa Espressif boards
- SMP support improvements for ESP32-S3
- Critical section handling improvements
Key architectural changes:
- IRQ Allocator: The new interrupt allocator enables multiple mapping
options from interrupt sources to CPU interrupts, providing flexibility
required by modern peripherals. Although this introduces breaking changes
to the interrupt handling API, the required ARCH_MINIMAL_VECTORTABLE
Kconfig option is explicitly checked during startup to ensure proper
configuration. This validation prevents runtime issues from configuration
mismatches.
- Xtensa-specific interrupt handling via esp_xtensa_intr.c providing
NuttX-native implementations of xt_ints_on/off and interrupt handlers,
avoiding conflicts with NuttX's core Xtensa macros.
- Timer/RTC unification: ESP32/ESP32-S2/ESP32-S3 move from chip-specific
RTC/RT-timer code to common-source Espressif integration, including
esp_timer_adapter/esp_rtc paths and the required bringup/defconfig updates.
- Power management consolidation: Xtensa PM follows the common-source
implementation, including common-source auto-sleep behavior, UART/Wi-Fi
wakeup coordination, and tickless-safe sleep flow compatibility.
Note: This is a large commit to maintain bisectability. Breaking the
changes into smaller commits would result in non-building intermediate
states across the common-source infrastructure update.
Tested configurations:
- All defconfigs were tested, including `ostest`.
