Heiner Kallweit 6b9352f3f8 pwm: meson: modify and simplify calculation in meson_pwm_get_state 
I don't see a reason why we should treat the case lo < hi differently
and return 0 as period and duty_cycle. The current logic was added with
c375bcbaab ("pwm: meson: Read the full hardware state in
meson_pwm_get_state()"), Martin as original author doesn't remember why
it was implemented this way back then.
So let's handle it as normal use case and also remove the optimization
for lo == 0. I think the improved readability is worth it.

Fixes: c375bcbaab ("pwm: meson: Read the full hardware state in meson_pwm_get_state()")
