dm: remove the dependency on native RTCT for vRTCT init

Browse Source 
virtual RTCT will be created on TCC driver interface, instead of
  pass-through native RTCT to ACRN user VMs.

  this patch removes dependency on native RTCT table:
   - rename build_vrtct() function to init_ssram()
     and minor changes inside.
   - drop function create_and_inject_vrtct()
   - add one API to get virtual RTCT table.
   - rename variable 'pt_rtct' to 'ssram'
