DS1WM: decouple host IRQ and INTR active state settings
The DS1WM driver incorrectly infers the IAS bit (1-wire interrupt active
high) from IRQ settings. There are devices that have IAS=0 but still need
the IRQ to trigger on a rising edge. With this patch, machines with DS1WM
that need IAS=1 have to set .active_high=1 in the ds1wm_platform_data.
