pwm: th1520: remove impl Send/Sync for Th1520PwmDriverData 

Now that clk implements Send and Sync, we no longer need to manually
implement these traits for Th1520PwmDriverData. Thus remove the
implementations.

// This `unsafe` implementation is a temporary necessity because the underlying `kernel::clk::Clk`
// type does not yet expose `Send` and `Sync` implementations. This block should be removed
// as soon as the clock abstraction provides these guarantees directly.
// TODO: Remove those unsafe impl's when Clk will support them itself.
// SAFETY: The `devres` framework requires the driver's private data to be `Send` and `Sync`.
// We can guarantee this because the PWM core synchronizes all callbacks, preventing concurrent
// access to the contained `iomem` and `clk` resources.
unsafe impl Send for Th1520PwmDriverData {}
// SAFETY: The same reasoning applies as for `Send`. The PWM core's synchronization
// guarantees that it is safe for multiple threads to have shared access (`&self`)
// to the driver data during callbacks.
