pwm: stm32: Replace write_ccrx with regmap_write
The TIM_CCR1...4 registers are consecutive, so replace the switch
case with a simple calculation. Since ch is known to be in the 0...3
range (it is set to hwpwm < npwm <= 4), drop the unnecessary error
handling. The return value was not checked anyway. What remains does
not warrant keeping the write_ccrx() function around, so instead call
regmap_write() directly at the singular call site.
