[nrf fromlist] drivers: sensor: qdec_nrfx: add conditional PM ISR safety

Requesting/releasing QDEC device may be ISR safe, but
it cannot be reliably known whether managing its power
domain is. Is is then assumed that if power domains are used,
device is no longer ISR safe. This macro let's us check if
we will be requesting/releasing power domains and determines
PM device ISR safety value.
