Define per-target SDIO slave descriptor buffer limits in the LL layer and validate queued send buffers against the 4-byte aligned effective maximum. Update the public docs to describe the chip-dependent limit instead of hardcoding 4092 bytes.

Adds CONFIG_SPIRAM_ENC_EXEMPT, available on chips that support per-page
PSRAM encryption configuration (esp32c5, esp32c61, esp32p4). When
enabled, esp_psram carves CONFIG_SPIRAM_ENC_EXEMPT_SIZE off the top of
PSRAM and maps it via the new mmu_hal_map_region_no_enc() helper, which
writes MMU entries without the SENSITIVE bit. The region is registered
as a separate heap pool reachable only through the new
MALLOC_CAP_SPIRAM_NO_ENC capability bit, so default SPIRAM allocations
cannot accidentally land there.
PSRAM encryption imposes alignment constraints that some DMA engines
(e.g. 2D-DMA) cannot satisfy. This option lets such workloads place
their buffers in unencrypted PSRAM while keeping the rest of PSRAM
(and flash) encrypted. Default disabled; security implications are
documented in the Kconfig help text.
In release/v5.x, esp_fault.h resides in the esp_hw_support (G1)
component, so the G0 components (hal, esp_rom) must not depend on it.
Copy its contents to esp_common as esp_fault_internal.h, keep
esp_fault.h as a compatibility wrapper around it, and switch the hal
and esp_rom ECDSA/ECC code to the internal header.
The addend in `emac_hal_ptp_start()` was derived from the floating-point
`config->ptp_req_accuracy_ns` instead of the integer `base_increment`
register that actually drives the sub-second update. The cast to
`uint8_t` loses the fractional part, so the un-corrected addend leaves
the PTP clock running off-rate.
Example: with a 40 MHz XTAL and the default `req_accuracy_ns = 40`,
`base_increment` rounds 85.899 up to 86, leaving the clock +1170 ppm
fast — well outside the IEEE 802.1AS neighborRateRatio limit (~±200
ppm), so strict-1AS bridges refuse asCapable.
Compute the addend from the stored `base_increment` for both rollover
modes: `addend = 2^32 * clk_period_ns / increment_ns`.
Measured on ESP32-P4: neighborRateRatio drops from +1147.5 ppm to
+4.2 ppm, and asCapable is granted.

The workaround in the commit routes the signal to LP GPIO matrix first.
When uses LP IOMUX pin as UART RX, the signal did not bypass the matrix,
which caused the issue.
This commit adds rtc_gpio_iomux_input and rtc_gpio_iomux_output APIs
to align with existing GPIO driver APIs.
This allows rtc_gpio_deinit to always switch the pad back to GPIO,
regardless of lp io clock enabled or not, so that gpio_config can
always switch the IO back to GPIO use after wakeup from deep sleep.
