isci: refactor initialization for S3/S4
Based on an original implementation by Ed Nadolski and Artur Wojcik In preparation for S3/S4 support refactor initialization so that driver-load and resume-from-suspend can share the common init path of isci_host_init(). Organize the initialization into objects that are self-contained to the driver (initialized by isci_host_init) versus those that have some upward registration (initialized at allocation time asd_sas_phy, asd_sas_port, dma allocations). The largest change is moving the the validation of the oem and module parameters from isci_host_init() to isci_host_alloc(). The S3/S4 approach being taken is that libsas will be tasked with remembering the state of the domain and the lldd is free to be forgetful. In the case of isci we'll just re-init using a subset of the normal driver load path.
