Rafael J. Wysocki fa5e295234 hpet: Check ACPI_COMPANION() against NULL at probe time ...

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
hpet driver.
