The VL53L0X can be powered using separate core (VDD) and I/O (VDDIO)
supplies. Add support for an optional vio regulator and enable/disable
it during power on/off when present.

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching. For bindings, the preferred subjects are
explained here:

There is no VDDIO pin. I checked on datasheet.

Last sentence is incorrect in this context. This patch is not doing that
and anyway, whatever your driver is doing is not here really that
relevant.
