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.
