Clarify the Rockchip PWM driver's error messages by referring to the clock
that operates a PWM device as the "PWM" clock, rather than the "bus"
clock (which is especially misleading in the case of devices that also use
a separate clock for bus access).

Hello Simon,

Maybe mention that this is the clock that is named "pwm" in the
devicetree and so matches to that, too.

Other than that the patch is fine.

Best regards
