lib: sbi: Introduce domain data

Browse Source 
Different parts of OpenSBI require their own per-domain data so
introduce domain data (or sbi_domain_data) which can be registered
by any part of OpenSBI. Using the domain data, the domain framework
will create a data pointer for every domain which can be used to
maintain some per-domain state.
