platform/chrome: chromeos_privacy_screen: Check ACPI_COMPANION()

Browse Source 
Every platform driver can be forced to match a device that doesn't match
its list of device IDs because of device_match_driver_override(), so
platform drivers that rely on the existence of a device's ACPI companion
object need to verify its presence.

Accordingly, add a requisite ACPI_COMPANION() check against NULL to the
chromeos_privacy_screen driver.
