Michal Wilczynski 264b501bb4 rust: pwm: Add module_pwm_platform_driver! macro
Rust PWM drivers using the abstractions in `kernel/pwm.rs` typically
call C functions (like `pwmchip_alloc`, `__pwmchip_add`, etc.) that are
exported to the `PWM` C symbol namespace.

With the introduction of `imports_ns` support in the `module!` macro,
every PWM driver would need to manually include `imports_ns: ["PWM"]` in
its module declaration.

To simplify this for driver authors and ensure consistency, introduce a
new helper macro `module_pwm_platform_driver!` in `pwm.rs`. This macro
wraps the standard `module_platform_driver!`, forwards all user provided
arguments using the `($($user_args:tt)*)` pattern, and automatically
injects the `imports_ns: ["PWM"]` declaration.

This follows the pattern used in other subsystems (e.g.,
`module_pci_driver!`) to provide specialized module registration
helpers. It makes writing PWM drivers slightly simpler and less error
prone regarding namespace imports.
