Fix two issues in ads1115_initialize():
1. Add missing kmm_free(priv) when adcdev allocation fails:
If the second kmm_malloc() for adcdev returns NULL, the function
returns without freeing the already-allocated priv structure,
causing a memory leak.
2. Use kmm_free() instead of free() for consistency:
The error path after cmdbyte_init() failure used free(priv) to
release memory allocated by kmm_malloc(). Use kmm_free() instead
to match the allocation API.

On some boards, the PCF85263 RTC does not count between reboots. Due to STOP_ENABLE (register 0x2E), bit=0 = 1, which freezes the RTC counter.
The exact trigger is unknown - not all boards exhibit the issue. The bit is battery-backed and
persists across reboots, so once set (e.g. by a power glitch or undefined hardware state) the
RTC stays frozen until explicitly cleared. The old driver never did this.
Fix: write `0x00` to `STOP_ENABLE` on init, which is the correct reset value per the datasheet.
Fix: set time properly:
Due to datasheet the set_time should be as follow:
1. set stop_enable
2. clear prescaler
3. set time
4. clear stop_enable

Fix two bugs in mcp3008_initialize():
1. Remove dead free(priv) when priv is NULL (line 382):
The first allocation checks if priv == NULL, then calls free(priv)
which is a no-op since priv is NULL. Remove the dead call.
2. Add missing kmm_free(priv) when adcdev allocation fails (line 396):
If the second kmm_malloc() for adcdev fails, the function returns
NULL without freeing the already-allocated priv, causing a memory
leak. Add kmm_free(priv) before the return.

mcp48xx_initialize() and mcp47x6_initialize() share the same two bugs
in their allocation error paths:
1. Dead code: when the first kmm_malloc() fails and priv is NULL, the
code calls free(priv) which is a no-op on NULL. Remove it.
2. Memory leak: when the second kmm_malloc() fails (dacdev), the
function returns NULL without freeing the already-allocated priv.
Add kmm_free(priv) before the return.

The STM32 serial drivers already treat 0 as not present for optional
GPIO fields (CTS, RTS), guarding each call site with a != 0 check.
TX and RX GPIO fields lacked this guard, so boards that
define GPIO_UARTx_TX or GPIO_UARTx_RX as 0 (pin not routed) caused
stm32_configgpio(0) to be called, which silently configures PA0 as a
floating input, corrupting any other peripheral using that pin.
Having an optional TX/RX UART is useful for several cases:
* RX-only connections: e.g. radio control input on flight-controllers where no TX is wired.
* Single-wire (half-duplex) connections: e.g. ESC telemetry connections.
* Output-only NSH which prints output but does not allow entering inputs.
Without a sentinel value for these cases one must assign the unused GPIO to
a NC pin, which is misleading when reading board configuration files.
Add != 0 guards for tx_gpio and rx_gpio across all STM32 serial driver
families.
Using 0 as the sentinel is safe for TX/RX because any valid UART config requires
GPIO_ALT bits set in the config word, so 0 can never represent a real
TX or RX pin configuration.

The RWDT register offsets were incorrectly set to ESP32-S3 values
instead of ESP32 values. This was introduced when the code was
refactored from using the local NuttX header hardware/esp32_rtccntl.h
(which had the correct offsets) to using the HAL library headers, and
the offsets were moved inline into esp32_wdt.c with wrong values.
Correct the offsets to match the actual ESP32 register layout from
soc/rtc_cntl_reg.h (RTC_CNTL_WDTCONFIG0_REG at 0x8c, INT_ENA at
0x3c, etc). Without this fix, all RWDT operations (enable, configure
timeout, enable interrupt, acknowledge interrupt, feed, write-protect)
were targeting wrong memory addresses, rendering the RWDT completely
non-functional.

Under the BOARD_LATE_INITIALIZE boot flow, rtc_clk_xtal_freq_get()
may return 0 (SOC_XTAL_FREQ_AUTO) because the XTAL frequency has
not yet been stored to the RTC register when the WDT driver is
initialized. This causes rtc_clk_cal() to divide by zero
internally (EXCCAUSE=0006) when computing the RTC slow clock
period.
Fix by explicitly calling rtc_clk_xtal_freq_update() with the
board's configured crystal frequency if rtc_clk_xtal_freq_get()
returns 0. Also add a guard in esp32_wdt_settimeout() to return
-EIO if ESP32_RWDT_CLK() still returns 0 cycles/ms, preventing
a subsequent divide-by-zero when computing the maximum timeout.

With the BOARD_LATE_INITIALIZE flow, board_late_initialize() runs
on a kernel thread and sets the MWDT0 prescaler. However, after it
returns, the init task (NSH) is spawned and lib_cxx_initialize()
invokes constructor functions, including
enable_timer_group0_for_calibration() from esp-hal-3rdparty which
calls timg_ll_reset_register(0), resetting all Timer Group 0
registers (including the WDT prescaler) back to their defaults.
Re-apply the prescaler, timeout, and feed the WDT counter in
wdt_lh_start() just before enabling the timer. This ensures
correct WDT configuration regardless of any intermediate register
resets by external code.
