PD#170850: unifykey: wrong unifykey driver init status

  The linux driver init order depends on init func level and
position in Makefile. Securitykey and unifykey are both
necessary for unifykey driver to work normal. Currently
securitykey is always initialized before unifykey, and the
unifykey init status checking API only checkes whether the
probe process of unifykey is done.So there is a chance when
LCD driver get unifykey probing process done status, while
securitykey is still under probing, which means unifykey
still cannot work normal
  We should switch the init order of these two module to
solve this issue
