qseecom: Add kernel space client support

Add support for kernel space client:
    - add support for starting secure app by kernel client
    - add support for shutting down secure app by kernel client
    - add support for sending command to secure app loaded by
      kernel space client(s)

The above is needed for allowing kernel modules to communicate
with app running in secure domain.
