pwm: core: use device_match_name() instead of strcmp(dev_name(...

Use the dedicated helper for comparing device names against strings.

Note, the current code has a check for the dev_name() against NULL.
With the current implementations of the device_add() and dev_set_name()
it most likely a theoretical assumption that that might happen, while
I don't see how. Hence, that check has simply been removed.
