This series adds support for the ToF proximity sensor installed on
Yoshino devices. As part of this series, support handling the reset
GPIO and VDD supply by the VL53L0X driver. Also stop hardcoding the
interrupt type, since on Yoshino devices it seems that edge triggering
doesn't work properly.
Tested on Sony Xperia XZ1 (poplar).

v2:
- Fix a nasty issue: turns out grouping the pinctrl makes it not apply,
which was the main cause of edge interrupts not working correctly and
having to use level interrupts, which caused a large amount of false
detections.
- handle the irq type more gracefully: if it's not provided, default
to falling edge, but if it's provided, then use the provided one.
v3:
- add irq.h header (forgot to commit)
- reword commit message (already initialized -> pre-initialized)
v4:
- reorder powering on and power off action (Jonathan)
- sort pinctrls by GPIO number (Konrad)
