ACPI / bind: Pass struct acpi_device pointer to acpi_bind_one()
There is no reason to pass an ACPI handle to acpi_bind_one() instead of a struct acpi_device pointer to the target device object, so modify that function to take a struct acpi_device pointer as its second argument and update all code depending on it accordingly.
