Currently, the domain initialization order is implied by the order in which domains are populated by sbi_platform_domains_init() from sbi_domain_finalize(). This is not documented anywhere and forces unecessary ordering between domain DT nodes. To address the above, introduce per-domain 32-bit integer to represent intialization order (aka "init_order") where domain with a lower initialization order will be booted first and two domains must not have same initialization order. For DT based domain creation, new "init-order" DT property can be used in domain DT node to specify the initialization order. The ROOT domain is assumed to have lowest initialization order (aka 0xffffffff).
