pwm: renesas-tpu: Make use of dev_err_probe()
The added benefit is that the error code is mentioned in the error message
and its usage is a bit more compact than open coding it. This also
improves behaviour in case devm_clk_get() returns -EPROBE_DEFER.
While touching this code, consistently start error messages with upper
case.
