Pull pwm updates from Uwe Kleine-König:
"This time around the pwm changes for the next release contain three
new drivers (loongson, mc33xs2410 and rzg2l-gpt) and the usual
collection of cleanups in both the core and drivers, support for new
variants in existing drivers, conversion of dt bindings to yaml and
documentation updates.

pwm: loongson: Fix u32 overflow in waveform calculation

mul_u64_u64_div_u64() returns an u64 that might be bigger than U32_MAX.
To properly handle this case it must not be directly assigned to an u32
value.

Use a wider type for duty and period to make the idiom:

duty = mul_u64_u64_div_u64(...)
if (duty > U32_MAX)
duty = U32_MAX;

actually work as intended.
