platform/x86: intel/smartconnect: Check ACPI_HANDLE() 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 a requisite ACPI_HANDLE() check against NULL to the
platform/x86 intel/smartconnect driver.
