lib: sbi: Extend sbi_hsm_hart_start() for domains
The sbi_hsm_hart_start() should consider the domain under which we
are trying to start the HART. This will help ensure that HART A can
start HART B only if both HARTs A and B belong to the same domain.
We also have a special case when we bring-up boot HART of non-root
domains in sbi_domain_finalize() where we should skip domain checks
in sbi_hsm_hart_start(). To achieve this, sbi_hsm_hart_start() should
do domain checks only when domain parameter is non-NULL.
This patch extends sbi_hsm_hart_start() as-per above.
