Subject: [PATCH 5.15 56/66] media: i2c: imx412: Fix power_off ordering

From: Bryan O'Donoghue <bryan.odonoghue@...aro.org>

commit 9a199694c6a1519522ec73a4571f68abe9f13d5d upstream.

The enable path does
- gpio
- clock

The disable path does
- gpio
- clock

Fix the order on the power-off path so that power-off and power-on have the
same ordering for clock and gpio.
