debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

Add board-level support for ES7210 4-ch ADC on lckfb-szpi-esp32s3:
- configs/es7210/defconfig: Board configuration with I2C0, I2S0,
ES7210 driver enabled. I2S pins: BCLK=14, DIN=12, MCLK=38, WS=13,
sample rate 48kHz.
- src/esp32s3_board_es7210.c: Board init registering ES7210 on I2C0
bus with I2S0 as audio transport
- src/esp32s3_bringup.c: Call ES7210 board init on startup; skip
generic I2S audio device registration on I2S0 when ES7210 is
enabled to avoid conflicting audio device on the same port
- src/esp32s3-szpi.h: ES7210 I2C address and device path defines
- src/Make.defs: Build integration for CONFIG_AUDIO_ES7210
Tested: 48kHz/2ch/16bit recording on ESP32-S3 (lckfb-szpi N16R8),
verified with nxrecorder and es7210_test.

Use static lower-half instances per timer and select the channel
through Kconfig and board data instead of passing runtime PWM
routing into the driver.
This keeps the HT32 PWM support aligned with the existing NuttX
pattern and documents the esk32 single-device TMR3 routing.

Add USB Video Class 1.1 gadget driver supporting Bulk transport
with uncompressed YUY2 video streaming. Resolution and frame
interval are negotiated dynamically via PROBE/COMMIT control.
- uvc.h: protocol constants, streaming control struct, public API
- uvc.c: class driver with PROBE/COMMIT, bulk EP, /dev/uvc0 chardev
- Kconfig/Make.defs: USBUVC config and build rules
- boardctl.c: BOARDIOC_USBDEV_UVC standalone init path
Hardened against host disconnect:
- Removed nxmutex_lock from USB interrupt context paths
- Added 30s semaphore timeout in uvc_write with EP_CANCEL fallback
- Drain stale wrsem counts in VS_COMMIT before new stream
- Guard uvc_streaming_stop() against double EP_CANCEL race
- Handle EP_SUBMIT returning -ESHUTDOWN gracefully

Remove the CONFIG_K210_WITH_QEMU option and associated conditional
code paths. The reasons for removal are:
* Simplifies code path for real hardware by removing QEMU workarounds
* The current QEMU target uses sifive_u machine, which is not designed
for K210 emulation
* For RISC-V QEMU simulation, the qemu-rv (rv-virt) target is a better
choice
* Renode can be used as an alternative for K210 simulation if needed

Add sysctl driver for K210 SoC providing clock and reset control:
- Clock enable/disable with two-stage APB/peripheral enable pattern
- Peripheral reset control with proper timing
- Clock frequency query for PLL, CPU, APB buses, and peripherals
- PLL frequency calculation and CPU frequency configuration
The sysctl driver is built unconditionally for K210 boards as it
provides essential clock and reset control functionality.
Add Kconfig option:
- K210_CPU_FREQ: Target CPU frequency in Hz (default 400MHz)

Three fixes to make LPUART1 work as NSH console on Nucleo-L552ZE-Q:
1. stm32l5_lowputc: add LPUART-specific BRR formula (256 * fCK / baud)
instead of reusing the standard USART divisor calculation.
2. stm32_boot: enable VDDIO2 and reconfigure LPUART1 GPIOs (PG7/PG8)
in board_initialize. The low-level setup runs before VDDIO2 is
enabled, so GPIOG writes silently fail.
3. stm32l5_serial: fix LPUART1 apbclock (PCLK1 not PCLK2), add
LPUART BRR branch in setformat, cast to uint64_t to prevent
32-bit overflow in (fCK << 8).
Also switch nsh defconfig from USART3 to LPUART1, add GPIO_LPUART1
pin definitions in board.h, and update board documentation.
