dm: add ssram support for user VM

Browse Source 
Hook ssram init && de-init functions to vdev
 devices lifecycle management:

 1) initialize ssram when vdev devices
    are initialized.

 2) de-initialize ssram when vdev devices
    are reset or destroyed.

 notes:
 ssram configuration data can be released only when
 user VM shutdown, hence it can't be done in deinit_vssram().

  - VM reboot:
    do deinit_vssram() only.

  - VM shutdown:
    do both deinit_vssram() and clean_vssram_config().
