Subject: [PATCH 3/4] pwm: th1520: Use module_pwm_platform_driver! macro

The `pwm_th1520` Rust driver calls C functions from the `PWM` namespace,
triggering `modpost` warnings due to missing namespace import
declarations in its `.modinfo` section.

Fix these warnings and simplify the module declaration by switching from
the generic `kernel::module_platform_driver!` macro to the newly
introduced PWM-specific `kernel::module_pwm_platform_driver!` macro.
The new macro automatically handles the required `imports_ns: ["PWM"]`
declaration.
