proximity: vl53l0x: Prefer pre-initialized interrupt flags

Browse Source 
On some boards interrupt type might be different than falling edge,
like hardcoded in driver. Leave interrupt flags as they were pre-configured
from the device-tree. If they're not provided, default to falling edge
interrupts.
