lib: sbi: Display domain details in boot prints
We extend boot prints to display details of each domain. In the process, we remove sbi_hart_pmp_dump() because it shows redundant information which domain details already show. Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Atish Patra <atish.patra@wdc.com>
