platform/x86: sony-laptop: Check ACPI_COMPANION() against NULL 
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 requisite ACPI_COMPANION() checks against NULL to the
platform/x86 sony-laptop driver.

Fixes: 14004dd31c ("platform/x86: sony-laptop: Convert NC driver to a platform one")
