Pull request overview

Tightens esp-metadata deserialization to catch TOML/schema mismatches earlier, and fixes a few concrete device-metadata mistakes that would otherwise be rejected once strict parsing is enabled.

Changes:

• Enforce #[serde(deny_unknown_fields)] on all driver configuration structs generated by driver_configs!.
• Remove/relocate invalid metadata keys in device TOMLs (esp32s2 GPIO signal max fields; esp32p4 GPIO mistakenly containing a DMA field).
• Fix esp32c61 SOC metadata to use cpu_csr_prv_mode and regenerate esp-metadata-generated outputs accordingly.

File	Description
esp-metadata/src/cfg.rs	Makes driver config structs reject unknown TOML fields to prevent silent metadata drift/typos.
esp-metadata/devices/esp32s2.toml	Removes input_signal_max/output_signal_max from [device.gpio] (these are computed, not specified).
esp-metadata/devices/esp32p4.toml	Removes misplaced separate_in_out_interrupts from [device.gpio] (DMA-only field).
esp-metadata/devices/esp32c61.toml	Replaces unused/incorrect SOC key with correct cpu_csr_prv_mode value.
esp-metadata-generated/src/_generated_esp32c61.rs	Regenerated property macro branches for the new SOC property.
esp-metadata-generated/src/_build_script_utils.rs	Regenerated build-script cfg/symbol emission for the new SOC property.
