The domain_support.md documentation states that "the HART to domain instance
assignment can be parsed from the device tree using *optional* DT property
opensbi-domain in each CPU DT node". However, the current implementation does
not treat this parameter as optional when determining which HARTs to assign to
a freshly discovered domain from the device tree, causing an effect where every
HART in the system must be explicitly assigned to a domain only if a domain is
specified in the device tree. Instead, this patch simply ignores CPUs that do
not specify a domain, and does not attempt to assign them into the recently
discovered domain.
