include: sbi: Add domains_init() platform operation
We introduce domains_init() platform operation which can be used by platform support to initialize/populate domains in the coldboot path. The domains_init() is called late in the coldboot sequence from the sbi_domain_finalize() so sbi_printf() can be used by platform support to print errors/warnings at time of populating domains.
