There are some unsolving issues on current 4.17 static shared memory
feature[1], including:
- In order to avoid keeping growing 'membank', having the shared memory
info in separate structures is preferred.
- Missing implementation on having the host address optional in
"xen,shared-mem" property
- Removing static shared memory from extended regions
- Missing reference release on foreign superpage
- Missing "xen,offset" feature, which is introduced in Linux DOC[2]

All above objects have been divided into two parts to complete. And this
patch serie is PART I.
