Add suspend / resume hooks for anx7625 driver, that power off the device
on suspend and power on the device on resume if it was previously
powered.
Signed-off-by: Pi-Hsun Shih <pihsun@xxxxxxxxxxxx>

Changes in v5:
* Disable irq and flush workqueue in suspend hook, so the irq handler
won't be run during suspend.
Changes in v3, v4:
* No change.
