bus: mhi: Add MMIO region length to controller structure
Make controller driver specify the MMIO register region length for range checking of BHI or BHIe space. This can help validate that offsets are in acceptable memory region or not and avoid any boot-up issues due to BHI or BHIe memory accesses.
