Mounting an automount configmap as subpath ignores binaryData field

[amisevsk]

Description

Mounting a configmap with .binaryData and controller.devfile.io/mount-as: subpath ignores keys in binaryData

How To Reproduce

Create a configmap

kind: ConfigMap
apiVersion: v1
metadata:
  name: test-cm
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-configmap: 'true'
  annotations:
    controller.devfile.io/mount-as: subpath
    controller.devfile.io/mount-path: /tmp/
binaryData:
  testfile: aGVsbG8K # "hello"

and note that testfile is not mounted to /tmp/testfile

Expected behavior

Subpath mounts should consider both binaryData and data.
