Many of the license and Intel copyright headers include the "All rights

license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

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().

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.

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'

guest ssram will be virtualized based on tcc driver interface,
instead of pass-thru native rtct, rename its source files to
avoid confusing:
- rename:
rtct.c -> vssram.c
rtct.h -> vssram.h
- move rtct.c from platform/acpci/ to platform/
- new directory 'vssram' to hold vssram source files.
