pwm: stm32-lp: Use regmap_clear_bits and regmap_set_bits where applicable 

Found using coccinelle and the following semantic patch:

@@
expression map, reg, bits;
@@

- regmap_update_bits(map, reg, bits, bits)
+ regmap_set_bits(map, reg, bits)

- regmap_update_bits(map, reg, bits, 0)
+ regmap_clear_bits(map, reg, bits)
