ACPI: HED: Switch over to devres-based resource management

Browse Source 
Use the newly introduced devm_acpi_install_notify_handler() for
installing an ACPI notify handler and since that function checks the
ACPI companion of the owner device against NULL internally, remove the
the explicit ACPI companion check from acpi_hed_probe().

No intentional functional impact.
