Add error message when probe() unable to get clks - Fixes bug when SoC is old mips which has no complex clock tree. if clocks not exist, use the new property from DT to apply period caculation; otherwise, use clk_get_rate to get clock frequency and apply period caculation. Changes since v3: - add a new property "clock-frequency" and fix mt7628 pwm - add mt7629 pwm support Changes since v2: - use num-pwms instead of mediatek,num-pwms. - rename the member from num_pwms to fallback_num_pwms to make it more obvious that it doesn't represent the actually used value. - add a dev_warn and a expressive comment to help other developers to not start adding num_pwms in the compatible_data. Changes since v1: - add some checks for backwards compatibility.
