ASoC: Fixes for v6.19

We've been quite busy with fixes since the merge window, though not in
any particularly exciting ways - the standout thing is the fix for _SX
controls which were broken by a change to how we do clamping, otherwise
it's all fairly run of the mill fixes and quirks.

The driver fails to build on configurations lacking COMMON_CLK (missing

ensure correct compilation and platform targeting.

pwm: airoha: Add support for EN7581 SoC

Introduce driver for PWM module available on EN7581 SoC.

Limitations:
- Only 8 concurrent waveform generators are available for 8 combinations of
duty_cycle and period. Waveform generators are shared between 16 GPIO
pins and 17 SIPO GPIO pins.
- Supports only normal polarity.
- On configuration the currently running period is completed.
- Minimum supported period is 4 ms
- Maximum supported period is 1s

pwm: Add Rust driver for T-HEAD TH1520 SoC

Introduce a PWM driver for the T-HEAD TH1520 SoC, written in Rust and
utilizing the safe PWM abstractions from the preceding commit.

The driver implements the pwm::PwmOps trait using the modern waveform
API (round_waveform_tohw, write_waveform, etc.) to support configuration
of period, duty cycle, and polarity for the TH1520's PWM channels.

Resource management is handled using idiomatic Rust patterns. The PWM
chip object is allocated via pwm::Chip::new and its registration with
the PWM core is managed by the pwm::Registration RAII guard. This
ensures pwmchip_remove is always called when the driver unbinds,
preventing resource leaks. Device managed resources are used for the
MMIO region, and the clock lifecycle is correctly managed in the
driver's private data Drop implementation.

The driver's core logic is written entirely in safe Rust, with no unsafe
blocks, except for the Send and Sync implementations for the driver
data, which are explained in the comments.

rust: pwm: Add Kconfig and basic data structures

Introduce the foundational support for PWM abstractions in Rust.

This commit adds the `RUST_PWM_ABSTRACTIONS` Kconfig option to enable
the feature, along with the necessary build-system support and C
helpers.

It also introduces the first set of safe wrappers for the PWM
subsystem, covering the basic data carrying C structs and enums:
- `Polarity`: A safe wrapper for `enum pwm_polarity`.
- `Waveform`: A wrapper for `struct pwm_waveform`.
- `State`: A wrapper for `struct pwm_state`.

These types provide memory safe, idiomatic Rust representations of the
core PWM data structures and form the building blocks for the
abstractions that will follow.
