Given that the sg2044 has more registers (to e.g. implement different
polarity), but the sg2042 registers are identical, I wonder if the 2044
device should use:

	compatible = "sophgo,sg2044-pwm", "sophgo,sg2042-pwm";

Note, I'm unsure here, only providing input to people who are more
knowledgeable in DT that I am.

Best regards
Uwe
