media: atomisp: ov2722: Fix GPIO1 polarity

The comment claims the PWDN pin is active when pulled down in other words,
it is /power-down so it needs to be driven high to get the sensor
powered-up (not powered down) and flag is 1 when powering-up the sensor
so the ! is wrong, drop it.

This also matches with the schematics which I have which shows GPIO1 also
enables a 3.3v line to the sensor-module which controls the privacy-LED
and indeed before this patch the privacy LED was inverted from what it
should be (and the sensor did not work).
