hwmon: (acpi_power_meter) 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 a requisite ACPI_COMPANION() check against NULL to the
acpi_power_meter hwmon driver.
