1) With this patch, '--ssram' option is updated to enable
vSSRAM feature support for ACRN user VMs.
'--ssram' argument of Device Model shall follow below format:
--ssram {Ln,vcpu=vcpu_set,size=nK|M;}
example:
--ssram L2,vcpu=0,1,size=4K;L2,vcpu=2,3,size=1M;L3,vcpu=all,size=2M
2) define data structure and variable
to store the configuration data for later processing.
3) add new API to cleanup configuration data when VM shutdown.
