[PATCH 1/9] lib: utils/ipi: Use sbi_domain_root_add_memrange() for ACLINT mswi

[Anup Patel <apatel@ventanamicro.com>]

The sbi_domain_root_add_memrange() should be preferred for creating
multiple memregions over a range. Update ACLINT mswi driver to use
sbi_domain_root_add_memrange() instead of explicity registering
memregions.
