[PATCH] drm/bridge: it6505: Fix return value check for pm_runtime_get_sync

[Pin-yen Lin]

`pm_runtime_get_sync` may return 1 on success. Fix the `if` statement
here to make the code less confusing, even though additional calls to
`it6505_poweron` doesn't break anything when it's already powered.

This was reported by Dan Carpenter <dan.carpenter at oracle.com> in
