Anup Patel e73b92d862 lib: sbi: Extend sbi_hsm_hart_started_mask() for domains
The sbi_hsm_hart_started_mask() API should take one more parameter
to allow caller specify domain under which started_mask is being
generated. Further, the sbi_hsm_hart_started_mask() depends on
sbi_hsm_hart_get_state() which also should return HART state under
specified domain.

This patch updates both sbi_hsm_hart_started_mask() and
sbi_hsm_hart_get_state() as-per above.
