I could imagine that we design a generic property for filters. The ones
above make me wonder, though, because they are bool. I'd think you can
configure the filters in some way, too?

I never used such filtering, so I am unaware of the parameters needed /
suitable. Quick grepping through I2C master drivers reveals that
i2c-stm32f7.c also handles filters, but only with default values. Maybe
DT configuration would be benefitial to that driver, too?
