Add ESP32-S31 USB DWC/UTMI LL headers, SoC register structures, peripheral
descriptors, capabilities, and linker mappings so the HS OTG controller and
UTMI PHY can be built in esp_hal_usb.
Introduce SOC_USB_FSLS_PHY_NUM on USB-OTG targets to separate FSLS USB_WRAP
support from OTG/UTMI support. Use it to gate usb_wrap, the USB PHY driver,
docs, and example build rules on targets without an FSLS PHY.
Also add UTMI data pulldown control to the HAL, clear the boot-time DWC
suspend state on ESP32-S31, alias the legacy internal PHY target to UTMI for
backward compatibility, and extend usb_phy tests for UTMI-only targets.
No esp32s31 boards are registered in the flash_suspend runner pool yet.
The test_rtc_clk_flash test targets all SOC_CLK_TREE_SUPPORTED chips and
creates a flash_suspend CI job for esp32s31 that immediately fails with
no runner assigned. Add a temp_skip_ci matching the existing pattern for
esp32h2.
Tracked in IDF-15531.

Add a dedicated esp_cpu test app that covers the supported helper APIs,
interrupt helpers, debug helper validation, and destructive trigger cases.
Made-with: Cursor
Treat ESP_INTR_FLAG_SHARED_PRIVATE as shared when selecting interrupt
lines and avoid misclassifying private shared vectors as non-shared
during free. Also fix two error-path leaks in esp_intr_alloc_info by
freeing the temporary handle and rolling back group_name on allocation
failure.
refactor(esp_hw_support): add semantic vector descriptor helpers
Introduce helper macros to classify vector descriptor state (shared,
non-shared, private shared, and uninitialized) and apply them in
allocator/free/dump paths. This makes private-shared semantics explicit
and reduces repeated bitwise checks.
Rename vector descriptor helpers to explicitly distinguish public
shared, private shared, and shared-family states. This improves
readability and avoids ambiguity when handling mixed shared/non-shared
flag combinations.
Re-enable ESP32S31 support for multiple test apps and examples:
- hw_support unity tests (with RWDT reset reason fix)
- eventfd example (select functionality)
- stdio test app
- console test app and examples
- startup_time example
- Removed conditional definitions for various RCC_ATOMIC macros across
multiple files, replacing them with a unified PERIPH_RCC_ATOMIC() macro.
- Updated instances where specific RCC_ATOMIC macros were used to ensure
consistent usage of PERIPH_RCC_ATOMIC().
- Deleted unused uart_share_hw_ctrl.h file as its functionality is now
integrated into the new structure.

rename SOC_GPIO_DEEP_SLEEP_WAKE_VALID_GPIO_MASK to SOC_GPIO_HP_PERIPH_PD_SLEEP_WAKEABLE_MASK
rename SOC_GPIO_DEEP_SLEEP_WAKE_SUPPORTED_PIN_CNT to SOC_GPIO_HP_PERIPH_PD_SLEEP_WAKEABLE_PIN_CNT
rename SOC_GPIO_SUPPORT_DEEPSLEEP_WAKEUP to SOC_GPIO_SUPPORT_HP_PERIPH_PD_SLEEP_WAKEUP
refactor(gdma): channel allocation can return both direction within the same call && Support ESP32-P4 ECO6
